  1. flash_partitions: a flash_map alternative 

    Working with partitions on a flash device has been done using the
flash_map subsystem. The flash_map subsystem has been limiting
(e.g. zephyrproject-rtos#52395) and does not support support for flash devices that
do not need an erase (non flash devices that are supported as if they
are flash).

The PR proposes an alternative for flash_map that supports classic flash
devices, "no-erase" flash devices. Partitions can be read-only, and it
is possible to provide an "override" erase-block-size.

The support for "no-erase" flash devices is achieved by the definition
of a "zephyr,flash-no-erase" compatible that is added to the flash
device.
