The original ROM function enabled output for the pad first, and then connected the signal
This could result in an undesired level change at the pad

There are some register description errors in parts of rom/gpio.h
This commit update the incorrect comments in rom/gpio.h And now
esp_rom_gpio.h is recommend instead of rom/gpio.h. So this commit adds
macro SIG_GPIO_OUT_IDX in esp_rom_gpio_connect_out_signal
function and removes the reference to gpio.h in some source files.

During HAL layer refactoring and new chip bringup, we have several
caps.h for each part, to reduce the conflicts to minimum. But this is
The capabilities headers will be relataive stable once completely
written (maybe after the featues are supported by drivers).
Now ESP32 and ESP32-S2 drivers are relative stable, making it a good
time to combine all these caps.h into one soc_caps.h
This cleanup also move HAL config and pin config into separated files,
to make the responsibilities of these headers more clear. This is
helpful for the stabilities of soc_caps.h because we want to make it
public some day.
