Dump more info in JitDump for HWIHNTRINSIC nodes (#115255)

In particular, dump `gtSimdSize` and `gtAuxiliaryJitType`.

Example:
```
old:
HWINTRINSIC simd64 long InsertVector128
HWINTRINSIC mask   long ConvertVectorToMask

new:
HWINTRINSIC simd64 64 long InsertVector128
HWINTRINSIC mask   64 long ConvertVectorToMask
```
