OvmfPkg/PlatformPei: increase memory type info defaults
Any new OVMF binary (containing commit d42fdd6f8384, and built with
SMM_REQUIRE) is likely to reboot during its first boot, regardless of
whether the variable store is logically empty, or it contains a
MemoryTypeInformation variable from an earlier OVMF binary.
This "reboot on first boot after OVMF upgrade" occurs despite having
eliminated BS Code/Data tracking in earlier parts of this series. Meaning
that we've outgrown the bins of those memory types too that matter for SMM
security.
Eliminating said reboot will make an upgrade to edk2-stable202005 more
comfortable for users. Increase the defaults empirically. (The total
doesn't exceed 3MB by much.)
