ESP32 SoC use a static allocated array as idle stack. To fit
the existed idle stack allocation, make idle stack allocated
from ebss for the whole esp32 series.

RTC data was not being correctly placed on RTC's memory data due to
linker issues. Also, the image's RTC memory segment was not being
properly parsed by the bootloader.
This commit implements the RMT peripheral for all the supported
Espressif's RISC-V devices. It also implements the support for the
WS2812 addressable RGB LED using the RMT peripheral.
This is a workaround commit to temporarily reduce the flash usage of
esp32c6 to avoid ci failure, Since I am not familiar with esptool,
and this issue cannot be reproduced in the local environment,
so I temporarily turn off related optimizations to save flash size.
