This patch introduces CBMEM ID to store the MRC version (similar to
existing implementation that stores the FSP-M version inside CBMEM ID)
inside cbmem so the version information is available across the
different coreboot stages. For example:
* romstage: Use the CBMEM ID version information to check if the MRC
cache is valid and need to erase the MRC cache
* ramstage: Use the CBMEM ID to store the MRC cache into the
non-volatile space.
BUG=b:261689642
TEST=Able to build and boot google/rex and dump the MRC version as
below.
