Daniel Leung 40ba4015e3 kernel: mm: only include demand_paging.h if needed
This moves including of demand_paging.h out of kernel/mm.h,
so that users of demand paging APIs must include the header
explicitly. Since the main user is kernel itself, we can be
more discipline about header inclusion.

Daniel Leung c972ef1a0f kernel: mm: move kernel mm functions under kernel includes
This moves the k_* memory management functions from sys/ into
kernel/ includes, as there are kernel public APIs. The z_*
functions are further separated into the kernel internal
header directory.

Also made a quick change to doxygen to group sys_mem_* into
the OS Memory Management group so they will appear in doc.

Anas Nashif 4e396174ce kernel: move syscall_handler.h to internal include directory
Move the syscall_handler.h header, used internally only to a dedicated
internal folder that should not be used outside of Zephyr.

Gerard Marull-Paretas cffefc818d kernel: migrate includes to <zephyr/...>
In order to bring consistency in-tree, migrate all kernel code to the
new prefix <zephyr/...>. Note that the conversion has been scripted,
refer to zephyrproject-rtos#45388 for more details.

Daniel Leung dfa4b7e375 kernel: mmu: z_backing_store* to k_mem_paging_backing_store*
These functions are those that need be implemented by backing
store outside kernel. Promote them from z_* so these can be
included in documentation.

Daniel Leung 31c362d966 kernel: mmu: rename z_eviction* to k_mem_paging_eviction*
These functions and data structures are those that need
to be implemented by eviction algorithm and application
outside kernel. Promote them from z_* so these can be
included in documentation.

This adds bits to the paging timing histogram collection routines
so they can use timing functions to collect execution time data.

Daniel Leung ae86519819 kernel: mmu: collect more demand paging statistics
This adds more bits to gather statistics on demand paging,
e.g. clean vs dirty pages evicted, # page faults with
IRQ locked/unlocked, etc.

Also extends this to gather per-thread demand paging
statistics.
