Brijesh Singh 11b15336f0 OvmfPkg/BaseMemEncryptSevLib: skip the pre-validated system RAM
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3275

The MemEncryptSevSnpPreValidateSystemRam() is used for pre-validating the
system RAM. As the boot progress, each phase validates a fixed region of
the RAM. In the PEI phase, the PlatformPei detects all the available RAM
and calls to pre-validate the detected system RAM.

While validating the system RAM in PEI phase, we must skip previously
validated system RAM to avoid the double validation.
