Debug FSP is ~920KiB larger than release FSP and we don't have
sufficient space for rex flash layout.
Remove RW_LEGACY and split them into RW_SECTION_A/B so we can have a
room for it.
Note: This fmd will only used for internal testing/debugging and not for
the firmware in released devices.
BUG=b:262868089
TEST=Build google/rex with CONFIG_BUILDING_WITH_DEBUG_FSP.
