google/kukui: Revise FMAP firmware layout
Adjust FMAP sections that
- ELOG only needs 4K (by driver limitation)
- SHARED_DATA only needs 4K or less (for netboot params)
- SMMSTORE is probably not needed since UEFI@ARM is not available yet
- VPD can be smaller (most x86 devices have only 16/8K for RO/RW)
- Increase RW_LEGACY to 1M (recommended value)
- Move all new saved space to CBFS
BUG=b:134624821
TEST=Built Kukui image and boots on Rev2 units.
