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.
When compiling for a chip target with Clang,
CMAKE_C_COMPILER_ID="Clang" but the linker is still a GNU linker.
Therefore we can still generate the map file.
Host tests of nvs_flash eligible to run in Linux implementation of nvs flash were migrated. Remaining test cases
were left in original folder. Migrated test cases use CMake instead of make.
This commit removes all kconfig_new files and references to them and adds esp-idf-kconfig as a dependency and adequate wrappers to avoid breaking changes.
This commit ads the corresponding --output-file option from idf_size.py to idf.py.
This is needed because piping the idf.py size output to a file would result in CMake output being present in the file as well.
Unlike COMPILE_OPTIONS, COMPILE_DEFINITIONS CMake property assumes
values without the -D prefix, such as NAME or NAME=VAL.
Previously, IDF build system was passing COMPILE_DEFINITIONS build
property to CMake COMPILE_OPTIONS property, so -D prefix was not
a problem.
Now that COMPILE_DEFINITIONS CMake property is used, -D prefix has
to be removed.
(Note that this doesn't affect 'target_compile_definitions' function,
which strips -D prefix before adding the definition to the property.)
Now that the supported CMake version is >=3.16, this code can be
simplified.
The code to deduplicate the directories can be removed since this is
handled by target_link_directories.

Setting this option informs CMake that it should pass
-fcolor-diagnostics flag to the compiler.
(Colorized build system output, like from GNU Make, is produced even
without this flag.)
Note that if the build is done using Ninja and the build output is
redirected (not a TTY), Ninja will still strip the escape codes from
the output. For the case of idf.py, this is handled in the next
commit.

This adds CSV support to idf_size.py and idf.py size actions and using the --format argument which accepts 'text', 'json' or 'csv' as input.
idf_size.py --json argument is deprecated but left to avoid a breaking change.
For idf.py size actions OUTPUT_JSON environment variable set at configuration time is overriden at target build time if --format is used.
Additionally, this commit refactors big parts of code, unified usage of json_dict and manually generated dictionaries for textual output and improves code quality in many parts.
