For mapping operations in sys_mm_drv_simple_map_region() and
sys_mm_drv_simple_map_array(), when there was an error with
mapping any pages, it would simple return an error, leaving
already mapped pages still mapped. This modifies the behavior
where any failure during the whole mapping operation will
unmap the already mapped pages.
This also modifies the remapping and moving functions to
reset mappings when error is encountered.
Fixes#73121

Some systems may need to query the available memory regions in runtime.
For those, this patch adds a simple API that memory management drivers
can implement to provide such discovery.
A small test also added to exercise the default, empty implementation.

There are cases when attributes of mapped virtual memory need
to be updated. E.g. in case there is loadable library/module
code loaded to the l2 memory then memory needs to be read-write.
After the code is loaded and is ready to be executed then
attributes of mapped memory should be updated to
read-only/executable without loosing memory contents.

In order to bring consistency in-tree, migrate all drivers to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to #45388 for more details.

This adds skeleton Kconfig/CMakeLists.txt and common implementation
of some sys_mm_drv_*() functions.
