OVMF: Update OVMF FD/FV build to minimize ROM size
* Only SEC is uncompressed now * The MAIN FV with PEI & DXE can easily shrink and grow as needed * The final output will now be OVMF.Fv rather than OVMF.fd * The final output size will be a multiple of 64kb git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9672 6f19259b-4bc3-4df7-8a09-765794883524
