[ARM] Add MVE add.sat costs

[dmgreen]

Summary

This adds some basic MVE sadd_sat/ssub_sat/uadd_sat/usub_sat costs, based on when the instruction is legal. With smaller than legal types that are promoted we generate shr(qadd(shl, shl)), so the cost is 4 appropriately.

[SjoerdMeijer]

Looks reasonable.
