1. Fix multilib PACBTI-M mapping …

   Follow up to [ARM-software#467](ARM-software#467).
   
   This patch fixes the multilib mapping for PACBTI-M.
   
   The PACBTI-M variant should also match to configurations where
   the branch protection is restricted to only one of PAC or BTI, like in
   `-mbranch-protection=bti` or `-mbranch-protection=pac-ret`. Before this
   patch, the variant would only match if both features were requested at
   the same time. This is safe to do because instructions from either
   feature have no effect if that feature is disabled at runtime.
   
   This change also replaces ocurrences of `-mbranch-protection=standard`
   by `-mbranch-protection=pac-ret+bti` because the latter is more
   explicit.
