[src] add rt_hw_cpu_id() wrapper API (#8894)

* [src] add rt_hw_cpu_id() wrapper API

rt_hw_cpu_id() is an unsafe API which should not be used by most codes
directly. It's error-prone because it must be used in proper context,
otherwise it can lead to errors and unpredictable behavior.

This patch adds a wrapper API for rt_hw_cpu_id() to address this risk.
It includes the context-checking functionality and provides a safer
alternative for obtaining CPU IDs, ensuring that it is used correctly
within the appropriate context.
