[PATCH 2/6] tools: Reorganize mkfwumdata tool into fwumdata_src directory

[Kory Maincent]

Update FWU metadata-related tools by moving mkfwumdata.c into a new
tools/fwumdata_src/ directory structure. This refactoring prepares for the
addition of the fwumdata runtime tool, which will allow editing FWU
metadata directly from the target.

The Kconfig and Makefile entries are also moved into separate files within
the new directory (Kconfig and fwumdata.mk respectively) to keep all FWU
metadata tool configurations together and improve maintainability.
