[PATCH] fwu-mdata: Allow multiple metadata storage drivers to be enabled

[Kory Maincent]

Change the Kconfig from a "choice" to a conditional block, allowing
multiple FWU metadata storage drivers to be selected simultaneously
instead of being mutually exclusive.

This enables systems with FWU metadata on different storage types
(e.g., both GPT-partitioned block devices and MTD devices) to have
both drivers compiled in. The board can then select the appropriate
driver at runtime based on the devicetree description.

The change converts FWU_MDATA to a menuconfig and replaces the
"choice/endchoice" block with "if FWU_MDATA/endif", making
FWU_MDATA_GPT_BLK default to 'y' for backward compatibility.
