timer_hal_capture_and_get_counter_value
should be placed in the IRAM for speed optimization
because the default ISR handler is placed in the IRAM.

The caches are disabled when reading/writing/erasing flash.
All CPUs should always execute code and access data from internal RAM.
Add an IRAM option to enhance the performance of LEDC.
Closes https://github.com/espressif/esp-idf/issues/11554
Add test configuration to run all tests with heap component in the flash.
Add reference to this new configuration in performance section of the documentation.
1. Remove RTC_CLOCK_BBPLL_POWER_ON_WITH_USB Kconfig option
During sleep, BBPLL clock always gets disabled
esp_restart does not disable BBPLL clock, so that first stage bootloader log can be printed
2. Add a new Kconfig option PM_NO_AUTO_LS_ON_USJ_CONNECTED
When this option is selected, IDF will constantly monitor USB CDC port connection status.
As long as it gets connected to a HOST, automatic light-sleep will not happen.

This commit adds a workaround for the TWAI listen only mode errata which is
present on the ESP32, ESP32-S2, ESP32-S3, and ESP32-C3. twai_get_status_info()
has also been updated to account for the fact that TEC/REC are frozen in
listen only mode.
Errata Description:
When the TWAI controller is put into listen only mode, it should not influence
the TWAI bus in any way (i.e., should never send a dominant bit). However,
on the targets listed above, the TWAI controller will send dominant bits in an
error frame (i.e., active error frame), even if the controller is set to listen
only mode.
Workaround:
We can force the TWAI controller into the error passive state on startup (by
setting the REC to >= 128). Since the TEC/REC are frozen in listen only mode,
the TWAI controller will remain error passive and only send recessive bits
(i.e., passive error frames), thus will not influence the TWAI bus.

esp-ringbuf funtion placement is now controlled by its own configs:
CONFIG_RINGBUF_PLACE_FUNCTIONS_INTO_FLASH and CONFIG_RINGBUF_PLACE_ISR_FUNCTIONS_INTO_FLASH
Closes https://github.com/espressif/esp-idf/issues/9198
The legacy driver can't handle the breaking change between esp chips
very well.
And it's not elegant to extend new feature like DMA, ETM.
The new driver can return a opaque handle for each RMT channel.
An obvious transaction concept was also introduced.
TX and RX functionalities are splited out.
