Mostly useless patch. All architectures have their own code for
atomic operations and don't use this fallback. Still, it's a trivial
locking setup and we might as well.

Each work_q object gets a separate spinlock to synchronize access
instead of the global lock. Note that there was a recursive lock
condition in k_delayed_work_cancel(), so that's been split out into an
internal unlocked version and the API entry point that wraps it with a
lock.

The validation checking recently added to spinlocks is useful, but
requires kernel-internals like _current and _current_cpu in a header
context that tends to be needed before those are declared (or where we
don't want them declared), and is causing big header dependency
headaches.
Move it to C code, it's just a validation tool, not a performance
thing.

We want a _Swap() variant that can atomically release/restore a
spinlock state in addition to the legacy irqlock. The function as it
was is now named "_Swap_irqlock()", while _Swap() now refers to a
spinlock and takes two arguments. The former will be going away once
existing users (not that many! Swap() is an internal API, and the
long port away from legacy irqlocking is going to be happening mostly
in drivers) are ported to spinlocks.
Obviously on uniprocessor setups, these produce identical code. But
SMP requires that the correct API be used to maintain the global lock.

These two spots were duplicating logic that is already done inside
_reschedule(), which is the cleaner, less dangerous API. Use it where
possible when outside the scheduler internals.

This test seems to be fine in the current master, but doing
development, it easily starts to overflow RAM of some boards and/or
crash due to stack checks. So, decrease the ramdisk (the biggest
eater of RAM here) from default 96K to 80K, and bump main stack
size proactively.

Hardcoded 96KB starts to overload RAM regions and fail CI tests.
Quick test shows that 80KB ramdisk is ok, (passes tests/posix/fs).
And of course, targets with wealth of RAM may want to use bigger
ramdisks.

Implemented tests for the new join and detach features.
- The first tests multiple join operations.
- The second tests trying to join a detached thread.
- The third tests abandoning a join when the thread is detached after
creation.

Implements osThreadJoin and osThreadDetach.
This implementation uses a semaphore to signal when a thread is
exiting so any join operations are signalled to continue. It supports
multiple join operations on a single thread, and ensures joins are
aborted if a thread is detached.

Since we know do DTS before Kconfig we should try and remove dts from
creating Kconfig namespaced symbols and leave that to Kconfig. So
rename CONFIG_CCM_<FOO> to DT_CCM_<FOO>.
