Update the Signal Interfaces documentation to include all
signals with configurable default actions and group them
by behavior for improved readability.
This reflects the current implementation in
sched/signal/sig_default.c.

Modify ARM64 architecture configuration to disable fork support in protected
build mode (BUILD_PROTECTED). Update ARCH_HAVE_FORK condition from
"!BUILD_KERNEL" to "!BUILD_KERNEL && !BUILD_PROTECTED", ensuring fork is
only available in flat/monolithic builds, not in protected kernel builds.

Update the hrtimer documentation to describe the hrtimer state machine,
which is introduced to handle safe cancellation and execution in SMP
environments.

Add a safe synchronous hrtimer cancel API, hrtimer_cancel_sync().
If the timer callback is currently executing, this function waits
until the callback has completed and the timer state transitions
to HRTIMER_STATE_INACTIVE.

As pull request apache#17200 & apache#17368 introduced support for scheduling sleep, a documentation is needed for different sleep interfaces.
This patch adds the description for sleep interfaces currently provided in NuttX, including Scheduled sleep(nxsched_sleep()...), Signal-scheduled sleep(nxsig_sleep()...), and Busy sleep(up_udelay()).

In certain cases, when the event-wait thread is awakened,
it needs to know the specific mask bit that triggered it,
so that it can branch to different paths accordingly.
This patch introduces the nxevent_getmask function to address this requirement.

There are cases that users do not want the event wait object to be allocated automatically
in the stack as a temporary varialbe in nxevent_tickwait, since multiple threads will
access the varialbe, they want to allocate the object as a global variable for safety
control or easy debug. To solve this problem, this patch add a new function nxevent_tickwait_wait
implementation to give user the chance to pass the global wait object to it.

Add support for pthread_{get|set}concurrency support.
NuttX uses 1:1 threading model (every pthread is a kernel-managed thread),
so this function has no real effect on the scheduling behavior.

This extension for the event group, to establish a connection between
named event groups and a task. The task may reference the event group
associated with a VFS-based name. Then the event group can be used
in subsequent calls to nxevent_wait() or nxevent_post().
This is an internal OS interface and should not be used by applications.

Events groups are synchronization primitives that allow tasks to wait
for multiple conditions to be met before proceeding. They are particularly
useful in scenarios where a task needs to wait for several events to occur
simultaneously.
