soc/intel/common/cse: Split CSE metadata into two CBFS files

This change splits CSE metadata structure (added to CBFS) into two
separate CBFS files (me_rw.hash and me_rw.version). Since `struct
cse_rw_metadata` is now used, it is dropped completely.

This change is being made in order to prepare for the upcoming changes
to stitch CSE binary at build time. Since the binary might not be
available pre-built, it complicates the order of operations for the
addition of CSE metadata structure and declaring hash and version as
CPPFLAGS_common. Instead rules can be enabled for individual CBFS file
targets for hash and version that ensure proper ordering as well.

TEST=Ensured that update works correctly on brya by forcing version
mismatch. In case of version match, no update is triggered.
