[AArch64] Split FeatureMTE to FEAT_MTE and FEAT_MTE2.
These extensions depend on each other as follows: mte -> mte2 Currently in LLVM FeatureMTE models both FEAT_MTE and FEAT_MTE2 lumped together. However the architecture does not mandate that both need to be implemented at the same time. Therefore it makes sense to split them. This will allow Function Multiversioning to enable backend features for 'memtag' (means FEAT_MTE in FMV) which was previously impossible. I have added an override for the user visible name of FeatureMTE2 ('memtag') to preserve the old semantics for backwards compatibility with command line, target attribute and assembler directives.
