Rearranges the k_mem_slab fields so that information that describes
how much of the memory slab is used is co-located. This will allow
easier of its statistics into the object core statistics reporting
framework.

Rearranges the sys_mem_blocks fields so that information that describes
how much of the memory block is used is co-located. This will allow

Refactors CPU usage (thread runtime stats) to make it easier to
integrate with the object core statistics framework.

Instead of placing both FIFOs and LIFOs into a common k_queue
type section, they are now placed into their own custom iterable
secitons. This is necessary when employing object cores as FIFOs
and LIFOs will be associated with different lists.

Creates a test to verify that kernel objects can be found within
the object core framework.

Creates a set of tests to verify that the top-level
k_obj_core_stats_xxx() routines behave as expected.
Note that this test is not meant to test the details
of the object core statistics operator function pointers.

Changing the name of the routine test_obj_core_stats_deregister()
to something shorter (test_obj_core_stats_dereg) has been found to
be a workaround to the issue identified in zephyrproject-rtos#61087.

accesses the k_mem_slab structure (due to changes from this PR).
