There is a bug in the rw_spinlock. Each time atomic_compare_exchange_strong(object, expected, desired) is executed, the value of object is assigned to expected, so the value of expected needs to be reset each time.

spinlock: add rspin_lock_count query interface
Add rspin_lock_count() function to query the current recursion count of a
recursive spinlock. This allows callers to inspect the lock state without
modifying it, useful for debugging and diagnostics.

Add support for managing hrtimers using a simple list. This approach
is more memory-efficient, as list nodes use less memory, and it is
preferable to an RB-tree when the number of hrtimers is relatively small.

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 disable all signal functionality to reduce footprint for NuttX.

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.
