OvmfPkg: Create additional PML1 entries for large SEV-SNP VMs
Edk2 was failing, rather than creating more PML4 entries, when they
weren't present in the initial memory acceptance flow. Because of that
VMs with more than 512G memory were crashing. This code fixes that.
This change affects only SEV-SNP VMs.
The code was tested by successfully booting a 512G SEV-SNP VM.
