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).
