BaseTools/tools_def: drop -mgeneral-regs-only for AArch64 CLANGDWARF
Commit 0df6c8c157af9 ("BaseTools/tools_def AARCH64:
avoid SIMD registers in XIP code")
adds -mgeneral-regs-only to GCC_AARCH64_CC_XIPFLAGS,
in order to avoid a bug present in certain versions of GCC.
This was never a problem for clang.
That's given the history of what the problem is.
Then we can describe how we fix it:
Change *_CLANGDWARF_AARCH64_CC_XIPFLAGS to set the required -mstrict-align
option instead of importing the whole GCC variable.
