Per TCBZ2372, clang on Linux emits a warning if an enum-typed variable
is compared with a constant outside of the range of the enum. Such
comparisons are performed in multiple locations in DXE core on
variables of type EFI_MEMORY_TYPE. This patch moves the OEM and OS
reserved types into the EFI_MEMORY_TYPE enum itself to resolve this
issue and improve readability. This commit does this for the BaseTools
copy of this enum.
