various GPIO pin events.

Add support for a "named event" trace. This trace is intentionally not
used by the system. The purpose of this trace is to allow driver or
application developers to quickly add tracing for events for debug
purposes, and to provide an example of how tracing subsystems can be
extended with additional trace identifiers.

Move the implementation of zsock_poll to zvfs_poll. This allows
other types of file descriptors to also make use of poll()
functionality even when the network subsystem is not enabled.
Additionally, it partially removes a dependency cycle between
posix and networking by moving functionality into a mutual
dependency.

TX time tracing tells how long it took from network packet
creation to when the stack got rid of it.
So the network stack allocates net packet, this is the
start time. The end time is when the packet is fully processed (sent)
by the network device driver.

RX time tracing tells how long it took from network packet
creation to when the stack got rid of it.
So the network device driver allocates net packet, this is the
start time. The end time is when the packet is fully processed.
Currently the limitation is that the RX time duration is used
for network packets that are tied to an open socket.

This reverts commit 93973e2ead.
PR #73978 introduced a regression.
Unfortunately this PR cannot be reverted without reverting also
Let's revert both PRs to stabilize main again towards the 3.7 release.

Add a delay parameter to asynchronous device runtim put. This allows
to delay the put operation what is useful to avoid multiple states
transitions.

Although there is nothing wrong with the existing code,
it doesn't permit individual bits to be set (or cleared).
This makes further changes slightly awkward.
Use a mask to restrict the bits set in an event.

Adds two routines to flush pipe objects:
k_pipe_flush()
- This routine flushes the entire pipe. That includes both
the pipe's buffer and all pended writers. It is equivalent
to reading everything into a giant temporary buffer which
is then discarded.
k_pipe_buffer_flush()
- This routine flushes only the pipe's buffer (if it exists).
It is equivalent to reading a maximum of "buffer size" bytes
into a temporary buffer which is then discarded.

When generating syscall wrappers, call a tracing macro with the id,
name, and all parameters of the syscall as params when entering and
leaving the syscall. This can be disabled in certain call sites
by defining DISABLE_SYSCALL_TRACING which is useful for certain
tracing implementations which require syscalls themselves to work.
Notably some syscalls *cannot* be automatically traced this way and
headers where exclusions are set are in the gen_syscall.py as notracing.
Includes a systemview and test format implementation.
Tested with systemview, usb, and uart backends with the string
formatter using the tracing sample app.
Debugging the trace wrapper can be aided by setting the TRACE_DIAGNOSTIC
env var and rebuilding from scratch, a warning is issued for every
instance a syscall is traced.
Automatically generating a name mapping for SYSVIEW_Zephyr.txt is a
future item as is documenting how to capture and use the tracing data
generated.

Threads may wait on an event object such that any events posted to
that event object may wake a waiting thread if the posting satisfies
the waiting threads' event conditions.
The configuration option CONFIG_EVENTS is used to control the inclusion
of events in a system as their use increases the size of
'struct k_thread'.
