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.

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.
