  [CostModel][AArch64] Add initial costs for `masked.compressstore` (#213712)

This adds an initial cost model for `masked.compressstore`. The tests
are based on `masked_expand_load.ll`, which covers all configurations
for the `expand`/`compact` instructions.

Note: Right now, we only report valid costs for `masked.compressstore`
operations that can be lowered with SVE1 (as that's all we handle ISEL
for at the moment).
