Arjav Patel e2f3950d45 libc: add support for C23 stdbit.h with bit manipulation macros 
- Introduced Kconfig options for stdbit.h, allowing architecture-specific and generic implementations.
- Added new documentation for stdbit.h, detailing its usage and configuration.
- Updated CMake and Makefile to handle the inclusion of stdbit.h based on configuration settings.

This enhances the NuttX library with optional C23 bit manipulation utilities, improving functionality for architectures that support it.
