  [AArch64] Add getVectorInstrCost Codesize costs handling. (#130946)

We have a lot of missing Codesize costs for vector operations. This
patch starts things off by adding codesize costs for getVectorInstrCost,
returning a single cost instead of the VectorInsertExtractBaseCost
(which is typically 2). Insert of a load are given a cost of 0 as they
use ld1, otherwise the cost is 1.
