Allocation of the temporary internal buffer will now repeat until a small enough buffer can be
allocated, and only fail if less than a 256 byte block of internal RAM is free.
Adds unit test for the same, and generic test utility for creating memory pressure.
Previously would try allocate buffer of minimum size 16KB not maximum size 16KB, causing
out of memory errors for any large reads, or if less than 16KB contiguous free heap.
Also, if using legacy API and internal allocation failed then implementation would abort()
instead of returning the error to the caller.
Added test for using large buffers in PSRAM.

Tests for external flash chips used to controlled by macros, one bin for
one chip. And tests are done manually. This commit refactored the test
so that all 3 chips can all run in single test.
There used to be dummy phase before out phase in common command
transactions. This corrupts the data.
The code before never actually operate (clear) the QE bit, once it finds
the QE bit is set. It's hard to check whether the QE set/disable
functions work well.
This commit:
1. Cancel the dummy phase
2. Set and clear the QE bit according to chip settings, allowing tests
for QE bits. However for some chips (Winbond for example), it's not
forced to clear the QE bit if not able to.
3. Also refactor to allow chip_generic and other chips to share the same
code to read and write qe bit; let common command and read command share
configure_host_io_mode.
4. Rename read mode to io mode since maybe we will write data with quad
mode one day.
esp_partition_register_external did not call load_partitions, so if
it was called before any call to esp_partition_find, then the main
partition table would never be loaded. Introduce new function,
ensure_partitions_loaded, and call it both from esp_partition_find and
esp_partition_register_external.

During coredump, dangerous-area-checking should be disabled, and cache
disabling should be replaced by a safer version.
Dangerous-area-checking used to be in the HAL, but it seems to be more
fit to os functions. So it's moved to os functions. Interfaces are
provided to switch between os functions during coredump.
When legacy mode is used, the coredump still fails during linking
because "esp_flash_init_default_chip", "esp_flash_app_init" and
"esp_flash_default_chip " are not compiled and linked.
Instead of using ``if`` macros in callers, these functions are protected
by ``if`` macros in the header, and also not compiled in the sources.
"esp_flash_default_chip" variable is compiled with safe default value.
