[x86] FMAP: Move RW_VPD section and add RW_SHARED section back
This patch moves the RW VPD section to the same place they live
at H2O and H2C for Stumpy and Lumpy, so we can preserve them more
easily when switching back and forth.
Also, add a RW shared section around the MRC cache and dev cfg,
so they get wiped by a recovery firmware update.
