This PCD holds the address mask for page table entries when memory
encryption is enabled on AMD processors supporting the Secure Encrypted
Virtualization (SEV) feature.
The mask is applied when page tables are created (S3Resume.c).

This commit will resolve the issue brought by r17744.
AsciiStrCpyS (PerfData->Token, PERF_TOKEN_SIZE, Token);
The above using of AsciiStrCpyS will cause ASSERT if Token is longer than
PerfData->Token. Therefore, AsciiStrnCatS is used here to resolve the
issue.

2. Add MODULE_UNI_FILE file that contains the localized Abstract and Description of a module.
a. Addresses an information gap between INF files and the UEFI Distribution Packaging Specification XML schema
b. There will be an associated update to UPT in BaseTools to consume MODULE_UNI_FILE and associated UNI file during UDP creation that performs the INF -> XML conversion.
c. There will be an associated update to UPT in BaseTools to produce MODULE_UNI_FILE and associated UNI file during UDP installation that performs the XML -> INF conversion.
3. Add Module Extra UNI file that provides the localized Name of a module.
a. [UserExtensions.TianoCore."ExtraFiles"] provides an easy method for a module to specify extra files not listed in [Sources] or [Binaries] sections to be added to a UDP without having to list the files in the UPT package information data file.
b. There will be an associated update to UPT in BaseTools to package up files listed in [UserExtensions.TianoCore."ExtraFiles"] during UDP creation.
c. UNI file contains localized name of a module to go along with the localized Abstract and Description from the MODULE_UNI_FILE.

S3RestoreConfig2() can optionally stack-switch to the SMM S3 Resume Entry
Point and ask it to transfer to S3ResumeExecuteBootScript().
Similarly, S3ResumeExecuteBootScript() stack-switches explicitly to the
boot script executor, and asks it to transfer to S3ResumeBootOs().
Currently the stack pointers specified for the SMM S3 Resume Entry Point
and the boot script executor to use for returning are derived from
addresses of the first local variables in S3RestoreConfig2() and
S3ResumeExecuteBootScript(), respectively.
Since (theoretically) the stack grows down as local variables are defined
and functions are called, the idea is presumably to allow the respective
callee to overwrite the caller's local variables. (The callees in
question can never return normally, only by explicit stack switching.)
Taking the address of "Status" is less portable than optimal however.
Compilers are free to juggle local variables at build time as they
please, including order and alignment on the stack. For example, when the
code is built for 64-bit PEI with gcc-4.8.2, the address of "Status"
trips up the alignment assertion in SwitchStack().
Let's align the address of "Status" down to CPU_STACK_ALIGNMENT
explicitly. If a compiler ensures such alignment and places "Status" at
the highest address automatically, then this change has no effect.
Otherwise, we'll prepare ReturnStackPointer values that (a) are correctly
aligned, (b) preserve the same amount or more (but never less) from the
caller's local variables than before, which should be safe.

SMM S3 resume may change memory cache type for flash memory range and thus RestoreS3PageTables() in which loops are executed to create page table would have negative performance impact on S3 resume. Move the call to RestoreS3PageTables() earlier before SMM S3 resume can avoid this issue.
