  builtins: honour `_M_ARM64` as `__aarch64__`

When clang is used as `clang-cl`, we use MSVC style macros. The spelling
of `__aarch64__` is converted to `_M_ARM64`. Account for this
alternative spelling in the conditional check. While in the area, add a
tertiary spelling of `__arm64__` to ensure that we catch more of the
variants.
