    arm: remove unnecessary armv9-a multilib variant [PR104144]

    Remove the armv9-a specific multilib variants.  Instead, arrange to
    use either the armv8-a multilibs or the armv7-a versions, depeding on
    the configuration.  This eliminates the need to have a version of gas
    that understands --march=armv9-a when building GCC.  Very little, if
    anything in the standard libraries directly uses Armv9-a features
    anyway.

    Also remove the +crc variant rules for Armv9-a.  CRC is an implicit
    part of Armv9-a, so doesn't have a explicit feature to handle it.
