Set the time limit to be long enough not to trigger too early. Do
not unlock after assert when doing the time limit test.

Spin locks held for any lengthy duration prevent interrupts and
in a real time system where interrupts drive tasks this can be
problematic. Add an option to assert if a spin lock is held for
a duration longer than the configurable number of microseconds.

Add some error test cases for spinlock, include:
1.Validate indentical spinlock cannot be used recursively.
2.Validate unlocking incorrect spinlock will trigger assertion.
3.Validate releasing incorrect spinlock will trigger assertion.

This test was written very early. Spinlocks are required for SMP
implementation. They couldn't be tested in terms of it, so the test
used the low level MP API instead. But of course that breaks if SMP
is actually working and the CPU is already started.
No need for that now. Just spawn a thread like any other, and filter
the test to run only on SMP systems.
Fixes#19319

Simple test of spinlock semantics. Bounce between two CPUs locking
and releasing, validating that nothing changes at unexpected times.
