OvmfPkg/ResetVector: move clearing GHCB in SecMain
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3275
In preparation for SEV-SNP support move clearing of the GHCB memory from
the ResetVector/AmdSev.asm to SecMain/AmdSev.c. The GHCB page is not
accessed until SevEsProtocolCheck() switch to full GHCB. So, the move
does not make any changes in the code flow or logic. The move will
simplify the SEV-SNP support.
