[edk2] [PATCH v2] UefiCpuPkg S3Resume2Pei: Fix ASSERT in WriteToOsS3PerformanceData

[Hao Wu]

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.
