mb/google/rex: Update FMD to support CBFS verification

This patch adds the required FMD changes to support the change
in cse_lite 'commit Ie0266e50463926b8d377825 ("remove
cbfs_unverified_area_map() API in cse_lite")' for CBFS verification.

These blobs were kept separate originally to avoid hash loading and
verification every time and hence save boot time.

With the change in cse_lite the ME_RW_A/B blobs are now part of
FW_MAIN_A/B and corresponding entries in FMD can be removed.

BUG=b:284382452
TEST=Build CB image for google/rex board and test CSE FW
update/downgrade with CONFIG_VBOOT_CBFS_INTEGRATION config enabled.
Also confirm there is no increase in boot time with this change.
