OvmfPkg: Enable APs to accept memory for TDVF

Browse Source 
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4172

TDVF APs once did nothing but spin around to wait for the Wakeup command.
This patch enables APs to handle the AcceptPages command. Once APs find
the AcceptPages command, it set its stack and jump to the function of
ApAcceptMemoryResourceRange (which will be introduced in the following
patch).
