Subject: [PATCH 1/1] EmbeddedPkg: Fix a build error in FwVol.c in X64 arch

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3814

CompressedDataLength is declared as UINTN which is UINT64 in X64 arch.
But the second parameter of UefiDecompressGetInfo() is declared as
UINT32. So a build error is triggered. To declare CompressedDataLength
as UINT32 to fix the build error.
