BaseTools/tools_def AARCH64: mark register x18 as reserved
The AArch64 ABI classifies register x18 as a platform register, which
means it should not be used unless the code is guaranteed to run on a
platform that doesn't use it in such a capacity.
GCC does not honour this requirement by default, and so we need to tell
it not to touch it explicitly, by passing the -ffixed-x18 command line
option.
