MdePkg/Include: Allow CPU specific defines to be predefined

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3308

The EDK II Build Specifications do not restrict the set of
CPU architectures that can be supported.  Remove places in
the EDK II that assumes a fixed set of CPU architectures.

Update EFI_REMOVABLE_MEDIA_FILE_NAME to allow it to be
predefined in tools_def.txt or a DSC file [BuildOptions]
section using a *_*_*_CC_FLAGS statement.

Add support for the following two defines.  If neither are
defines, then preserve the current behavior.  If either is
defined, then compare these 16-bit values to Machine in the
EFI_IMAGE_MACHINE_TYPE_SUPPORTED(Machine) and
EFI_IMAGE_MACHINE_CROSS_TYPE_SUPPORTED(Machine) macros.

* EFI_IMAGE_MACHINE_TYPE_VALUE
* EFI_IMAGE_MACHINE_CROSS_TYPE_VALUE
