EmulatorPkg: Remove use of IntelFrameworkModulePkg legacy libs

LzmaCustomDecompressLib and PeiDxeDebugLibReportStatusCode were copied
from IntelFrameworkModulePkg to MdeModulePkg, but the originals were
kept for compatibility.

Since the libraries are identical, move EmulatorPkg to use the
MdeModulePkg versions instead.
