[AArch64] Add "FULL" to SVE mode iterator names

An upcoming patch will make more use of partial/unpacked SVE vectors.
We then need a distinction between mode iterators that include partial
modes and those that only include "full" modes.  This patch prepares
for that by adding "FULL" to the names of iterators that only select
full modes.  There should be no change in behaviour.
