Fixed an obvious mistake in the description of the return value of the
sys_mm_drv_unmap_region function.

() Put the memory bank APIs under the memory management group.
() Document the struct sys_mm_drv_bank.
() Put proper in,out for function parameters.

The macro SRAM_BANK_PAGE_NUM is specfic to the mtl_tlb
driver and is not universal. So move that from public
header into the driver.

Refines the `system_mm.h` to include `zephyr/types.h` instead
of `zephyr/kernel.h` as that is all it needs.
Updated the includes of `mm_drv_ti_rat.c` accordingly.

Removed the unneccessary casts in the functions to remove warnings
during build for SoCs using RAT. Functionality reamins the same,
tested on board.

Added Region based Address Translation (RAT) module driver. Required by
a few Texas Instruments SoCs to fucntion. Uses
sys_mm_drv_page_phys_get() API with device_map() for address translation.

The initial implementation was broken during improvements.
There was incorrect assumption that all pages are unmapped at
initials state. In reality at the beginning whole memory is
powered on, so we should mark all pages as mapped. Later in
initialization code unused pages are unmapped and if after this
some banks become empty (all pages unmapped), the power is
switched off.

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 includes within
include directory to the new prefix <zephyr/...>. Note that the
conversion has been scripted, refer to zephyrproject-rtos#45388 for more
details.

Move include paths and add new target_include_directories to support
backwards compatibility:
* /include -> /include/zephyr
example: <irq.h> -> <zephyr/irq.h>
