This commit enables the standad VERSION argument for the project() macro
in ESP-IDF. The VERSION argument is compilant with the requirements of
cmake 3.16. This commit also adds new test cases for verifying the
validity of the version argument.

Add new "all_component_info" dictionary into the
project_description.json file. It contains information about all
registered components presented in the __COMPONENT_TARGETS list.
Since components in this list are not fully evaluated, because only the first
stage of cmakefiles processing is done, it does not contain the same information
as the "build_component_info" dictionary. The "type", "file" and "sources" variables
are missing.
Most of the properties are already attached to the component target, so
this only adds INCLUDE_DIRS property to the target during the first cmakefiles
processing stage.
The "all_component_info" dict is generated in a separate function, even
though the original function for "build_component_info" could be
adjusted. This introduces a little bit of boilerplate, but keeps it
logically separated and probably easier if we want to extend it in the
future.

This extends information provided in the project_description.json file.
Newly added information can be used in the SBOM generating tool and
also to improve hints regarding the the component dependency issues.
Added fields
version:
This adds versioning to the project_description.json file,
so it's easy to identify if it contains the required information.
project_version:
Can be used as a version for the resulting binary e.g. `hello_world.bin`.
idf_path:
This one is probably not necessary, but it allows tools to run even without
esp-idf environment exported(e.g. export.sh).
c_compiler:
The `CMAKE_C_COMPILER` value with full path to the compiler binary. This can
be used to get information about toolchain, which was used to build the project.
common_component_reqs:
List of common components as presented in cmake's __COMPONENT_REQUIRES_COMMON
and set in tools/cmake/build.cmake:__build_init().
build_component_info:
Detailed information about components used during build. It's a
dictionary with the component name as a key and each component has
a dictionary with detailed information. Following is an example for
the efuse component.
"efuse": {
"alias": "idf::efuse",
"target": "___idf_efuse",
"prefix": "idf",
"dir": "/home/fhrbata/work/esp-idf/components/efuse",
"type": "LIBRARY",
"lib": "__idf_efuse",
"reqs": [],
"priv_reqs": [ "bootloader_support", "soc", "spi_flash" ],
"managed_reqs": [],
"managed_priv_reqs": [],
"file": "/home/fhrbata/work/blink/build/esp-idf/efuse/libefuse.a",
"sources": [ "/home/fhrbata/work/esp-idf/components/efuse/esp32s3/esp_efuse_table.c", ... ],
"include_dirs": [ "include", "esp32s3/include" ]
}

Currently make_json_list() returns '[ "" ]' for empty cmake list. Fix this
so empty json list is returned instead.

* reverted old faulty mechanism to set different
standard according to the toolchain
* Using -std=gnu++2b now for both gcc and clang
* Added a build test app to check the C++ standard in IDF
* Updated english docs to reflect the change to C++23
ADDITIONAL_MAKE_CLEAN_FILES is deprecated and only worked with make.
Replaced with the new ADDITIONAL_CLEAN_FILES (CMake 3.15) which also works with ninja.
This commit removes all idf_size.py files and references to them and adds esp-idf-size as a dependency and adequate wrappers to avoid breaking changes.
Currently the set-target has sdkconfig file name hardcoded to the
default one and doesn't honor custom config paths or names.
IMHO the only place where we can really now the config file name
is in cmake. But also the config should be really renamed only if
the set-target action is running.
This moves the config file renaming into cmake and it's performed only
when _IDF_PY_SET_TARGET_ACTION env. var. is set to 'ON'. This should
hopefully guarantee that it's really renamed only while set-target is
running.

Extend target checks in cmake, in case it's run directly and not via
idf.py or if idf.py misses something. This may happen
for example if cmake variables are set in project's CMakeLists.txt.
Some clean-ups are included along with the new checks and tests.
1. __target_check() function is removed. IIUC it should never fail,
because the selected target is explicitly passed as environmental
variable to kconfgen. Meaning the IDF_TARGET from environment variable may
not be actually used in kconfgen if IDF_TARGET is already set it cmake cache.
Note that the IDF_TARGET environment variable used for kconfgen is not
based on the actual IDF_TARGET environment variable set for idf.py, but
rather on the value set in __target_init() with
set(IDF_TARGET ${env_idf_target} CACHE STRING "IDF Build Target")
My understanding is that the original check was introduced to handle
situation, where IDF_TARGET was already set in cmake's cache and
the IDF_TARGET from environment variable was different. Since
the kconfgen would use the original environment variable(not
explicitly passed as it is now) the IDF_TARGET in cmake and in
sdkconfig could differ. IOW I think the original check was introduced
to cope with the following cmake behaviour
set(VARIABLE "value1" CACHE STRING "test variable")
set(VARIABLE "value2" CACHE STRING "test variable")
message("Variable value: ${VARIABLE}")
output: Variable value: value1
2. I scratched by head how it is possible that the following code
in __target_check()
if(NOT ${IDF_TARGET} STREQUAL ${env_idf_target})
could fail if IDF_TARGET is not set. For example in clean project
IDF_TARGET=esp32 idf.py reconfigure
Here env_idf_target==esp32 and IDF_TARGET is not set, so I would
expect that cmake will fail with error message that the cache
and env target do not match. The thing is that the variable
evaluation is done before the if command, so it actually
sees this
if(NOT STREQUAL esp32)
which is false and the error is not printed. It can be seen
with 'cmake --trace-expand' command. I don't know if this
was used on purpose or it worked just as a coincidence, but
I find it very confusing, so I added explicit check if the
IDF_TARGET is defined before the actual check. Same for
CMAKE_TOOLCHAIN_FILE.
3. Error messages are not formated(line-wrapped) by cmake's markup
so it's easier to check the output in tests.

The _guess_or_check_idf_target() function has sdkconfig and sdkconfig.defaults
file names hardcoded. Since config file names may be specified with SDKCONFIG
or SDKCONFIG_DEFAULTS cmake vars, directly in CMakeLists.txt or passed in with
the -D cmake option, they are not respected.
Problem is when SDKCONFIG or SDKCONFIG_DEFAULTS is set in
CMakeLists.txt. While idf can detect cmake vars passed through it
to cmake via the -D option, detecting SDKCONFIG and SDKCONFIG_DEFAULTS
vars settings in CMakeLists.txt would require to parse it. This seems
like error prone approach. Also if the vars defined by the -D option
are passed directly to cmake, not via idf, they will not be visible to idf.
It seems reasonable to move the logic into cmake, where we know the correct
SDKCONFIG and SDKCONFIG_DEFAULTS values. So the IDF_TARGET detection/guessing
is moved into targets.cmake, where the IDF_TARGET is actually set. The target
is guessed based on the following precendence.
1) $ENV{IDF_TARGET}
2) IDF_TARGET
3) SDKCONFIG
4) sdkconfig
5) SDKCONFIG_DEFAULTS if non-empty or
$ENV{SDKCONFIG_DEFAULTS} if non-empty or
sdkconfig.defaults
6) esp32
All config files referred in $ENV{SDKCONFIG_DEFAULTS} and SDKCONFIG_DEFAULTS
are searched, compared to the current behaviour. First target found in the
above chain is used.
The original _guess_or_check_idf_target() is renamed to _check_idf_target() and
used for the target consistency checks only.
The get_sdkconfig_filename() helper is now used to get the sdkconfig file
for consistency checks. It looks in SDKCONFIG specified with the -D
option and project_description.json.
With this change config full paths are reported in messages, so it's clear
e.g. from which config the target was guessed from or which config has
consistency problem. test_non_default_target.py was adjusted to this
change and also new test for testing the IDF_TARGET guessing was added.

Checking that the host is macOS is not sufficient here, since the
linker is still a GNU linker when cross-compiling for a chip.
Instead, use the linker_type variable introduced in the previous
commit.
