fix(cm): remove ENABLE_FEAT_MTE usage

commit@c282384dbb45b6185b4aba14efebbad110d18e49
removed ENABLE_FEAT_MTE but missed its usage in
context structure declaration path.

All mte regs that are currently context saved/restored
are needed only when FEAT_MTE2 is enabled, so move to
usage of FEAT_MTE2 and remove FEAT_MTE usage
