18091976ec fix(hal): Wrap LL macros with atomic env in do-while for control safety 
- Standardize all LL macros using atomic env variables with `do { ... } while (0)`
- Prevent potential macro misuse in control flow constructs (e.g., if/else)
- Affected targets: esp32, esp32c2, esp32c5, esp32s3, esp32p4, etc.
- Affected modules include: LCD, I2S, TIMER, and others

Merges https://github.com/espressif/esp-idf/pull/12093

fix(ll): remove FLAG_ATTR macro

Such kind of operator overload will not work because C++ thinks such overload is ambiguous and it still prefer the built-in one which accepts and returns integer. Manually force type conversion seems to be unavoidable.

d1993c01f2 hal/uart_ll.h: Fix compile with C++ 
I'm including <hal/uart_ll.h> in my C++ application because I need to
bypass the uart driver. The inline functions in the header file fail to
compile as C++.

All of the enums need explicit casts for conversion to/from integers.

874a720286 soc/ll: workaround compiler bug that generate 8/16 bits inst instead of 32 bits one 
update all struct headers to be more "standardized":

- bit fields are properly wrapped with struct
- bitwidth sum should be 32 within same struct, so that it's correctly padded with reserved bits
- bit field should be uint32_t
- typedef volatile struct xxx{} yyy;: xxx must exists. refer: https://github.com/espressif/esp-idf/pull/3199

added helper macros to force peripheral registers being accessed in 32 bitwidth

added a check script into ci

647dea9395 soc: combine xxx_caps.h into one soc_caps.h 
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.
