In Log V2, ESP_LOG macros are using the runtime
constrained-environment path in esp_log_vprintf() reference
esp_rom_vprintf as the fallback formatter. On chips where ets_vprintf
is not in ROM (all targets except ESP32-S2 and ESP32-C2), this pulls
~1.2 KB of printf implementation into IRAM.
Add a new Kconfig option LOG_API_CONSTRAINED_ENV_SAFE (default y) that
controls whether this IRAM-resident fallback is used:
Also update the logging and RAM-usage documentation accordingly.

Result from an example in 11057:
When this option is not enabled:
1000 iterations took 10914 microseconds (10.9 microseconds per invocation)
1000 iterations took 10909 microseconds (10.9 microseconds per invocation)
When this option is enabled:
1000 iterations took 10960 microseconds (10.9 microseconds per invocation)
1000 iterations took 107 microseconds (0.1 microseconds per invocation)
This commit adds a CHOOSE_MACRO_VA_ARG() selector to allow selection between two
versions of a macro based on the number of arguments. This replaces the previous
portGET_ARGUMENT_COUNT() selector.
- portYIELD_FROM_ISR() now uses CHOOSE_MACRO_VA_ARG()
- portYIELD_FROM_ISR(arg) version added to risc-v port
- Old vPortEvaluateYieldFromISR() and portGET_ARGUMENT_COUNT removed
This commit updates the chip independent system chapters of the
programming guide for esp32s3.

The following files have been ported:
* esp_rom_crc.h
* esp_rom_sys.h
* esp_rom_efuse.h (mostly no-ops)
* esp_rom_md5.h
Integrated Linux-based rom implementation into log
and NVS component.
Added brief host tests for ROM to ensure basic
consistency on Linux.
Added ROM printf host unit tests.
Temporarily added reset reason for Linux in ROM.
* ##__VA_ARGS__ is replaced by __VA_OPT__(,)
and __VA_ARGS if C++20 is used.
* Affected header files are: esp_log.h,
portmacro.h and esp_check.h
* Closes https://github.com/espressif/esp-idf/pull/6692
Main change is possibility the log cache locking functions will
be called before the scheduler has started.
This change doesn't change the behaviour of ESP_EARLY_LOGx, this is
done in the following commit.
Closes https://github.com/espressif/esp-idf/issues/5542
