wangchengdong 0ea686bc5b sched/signal: Add support for partially disabling signals 
Signals in NuttX serve two primary purposes:

    1. Synchronization and wake-up:
    Signals can be used to block threads on specific signal sets and later
    wake them up by delivering the corresponding signals to those threads.

    2. Asynchronous notification:
    Signals can also be used to install callback handlers for specific signals, allowing threads to
    asynchronously invoke those handlers when the signals are delivered.

This change introduces the ability to partially disable signal functionality: to disable only signal functions for
Asynchronous notification, keeping functions for Synchronization and wake-up.
This enables finer-grained control over signal usage while preserving existing behavior for supported use cases.
