For boot performance dump, as current behavior.
It depends on which PerformanceLib instance the DP application linked to.
For example, if DxePerfrmanceLib(MdeModulePkg\Library\DxePerformanceLib)
got linked, it will try to dump PEI and DXE performance data; and if
DxeSmmPerfrmanceLib(MdeModulePkg\Library\DxeSmmPerformanceLib)
got linked, then SMM performance data are expected.
It has burden and confusion to developers about the DP application need to be
linked to
different PerformanceLib instance in *.dsc and rebuilt for the performance data
dump.
