EmulatorPkg: Update UefiDecompressLib instance

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1683

BaseUefiDecompressLib in MdePkg is the
base UEFI decompress Library.
BaseUefiTianoCustomDecompressLib in IntelFrameworkModulePkg
implements the base UEFI decompress functionality and Tiano
decompress functionality.
Platform doesn't use the TianoCompress, so do
not have to use BaseUefiTianoCustomDecompressLib,
can use the BaseUefiDecompressLib in MdePkg directly.
