OvmfPkg/ResetVector: move SEV specific code in a separate file

Browse Source 
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3275

The PageTables64.asm was created to provide routines to set the CR3
register for 64-bit paging. During the SEV support, it grew to include a
lot of the SEV stuff. Before adding more SEV features, let's move all
the SEV-specific routines into a separate file.

No functionality change intended.
