  [instcombine] Extend logical reduction canonicalization to scalable vectors (#99366)

These transformations do not depend on the type being fixed in size, so
enable them for scalable vectors too. Unlike for fixed vectors, these
are only a canonicalization - the bitcast lowering for and/or/add is not
legal on a scalable vector type.
