The commit fixes issue where flash_area_flatten has been used where
code was only supposed to erase devices by hardware requirement prior
to write, by replacing the call with flash_area_erase and supporting
logic to select proper path.
There have been following Kconfig options added:
- CONFIG_BT_MESH_BLOB_IO_FLASH_WITHOUT_ERASE
- CONFIG_BT_MESH_BLOB_IO_FLASH_WITH_ERASE
that are available for user depending on devices in the system and allow
to turn off paths that are not used by BLOB IO; for example if user
never writes to device with erase CONFIG_BT_MESH_BLOB_IO_FLASH_WITH_ERASE
will disable the path.
Both Kconfig options are y by default and enable all paths.

The MBT server, as the MBT client currently sets the maximum chunk size
according to maximum supported segments in the accesss layer. This might
be suboptimal for some use cases.
The added Kconfig options give customers the option to fine tune it
themselves.
Future work will include addition of an API for the customer to modify
it also during runtime.

The flash_area_erase has been replaced with flash_area_flatten,
allowing code to work with devices that do not provide
erase callback.

Adapts flash writing for BLOB IO to RRAM. The previously used write
block alignment is not needed for RRAM.

Mode affects access to flash aread for `block_start`. When mode is set
to `BT_MESH_BLOB_READ` function return early, and because
`BT_MESH_BLOB_READ = 0` this is default behaviour. For write flash area
must be erased to allow driver to write there new data - bits can only
be pulled down, so overwrite will not be permitted.
