PerformancePkg Dp_App: Fix ASSERT in GetNameFromHandle 

This commit will resolve the issue brought by r17745.

StrCpyS (mGaugeString, DP_GAUGE_STRING_LENGTH + 1, StringPtr);

The above using of StrCpyS will cause ASSERT if StringPtr is longer than
mGaugeString. Therefore, StrnCpyS is used here to resolve the issue.

Similar scenario is for:
StrCpyS (mGaugeString, DP_GAUGE_STRING_LENGTH + 1, NameString); (twice)
