Added `-msve-vector-bits=<bits>` flag. If specified the `__ARM_FEATURE_SVE_BITS__EXPERIMENTAL` macro is defined and a language option `ArmSveVectorBits` is set. The language option replaces the macro parsing in SemaType for the attributed type and the macro tests have been removed. Now that the `-msve-vector-bits` flag is implemented in this patch, the final patch in the series is intended to make the feature macro non-experimental.
