EmulatorPkg: spurious failure in WriteBlocks on X64HEADmaster
WinNtBlockIoWriteBlocks can spuriously fail on X64. This occurs because &BytesWritten is a `UINTN*` (i.e. `UINT64*`) but is cast to `LPDWORD` (i.e. `UINT32*`). Only the low 32 bits are initialized by WriteFile, so the high 32 bits are uninitialized. This means we will spuriously fail the `BytesWritten != BufferSize` test. This doesn't occur on X86-32 since UINTN is the same as DWORD in that case. Fix is to declare BytesWritten as DWORD to match the type expected by WriteFile. This also makes the cast unnecessary.
