[vectorIntrinsics+mask] RFR: 8273264: AArch64: [vector] Add missing rules for VectorMaskCast

[Eric Liu]

This patch
1. Adds missing rules for VectorMaskCast for compatible species, E.g.
   ByteVector.SPECIES_64 --> ShortVector.SPECIES_128
2. Fixes a matching failure on AArch64.

The performance improves about 60% compared with the unintrinsified
version.
