  Log Message:
  -----------
  [DAGCombine] Change isBuildVectorAll* -> isConstantSplatVectorAll* for Vselect (#147305)

Change isBuildVectorAll* -> isConstantSplatVectorAll* in VSelect in case
the fold happens after BuildVector has been canonically transformed to
Splat or if the Splat is initially in vselect already

- Fixes #73454
- Update related test cases, add extra tests in wasm
