  [MLIR][Vector] Remove vector.splat (#162167)

vector.splat has been deprecated (user: please use the very similar vector.broadcast instead) 
with the last PR landing about 6 weeks ago.

The discourse discussion is at
https://discourse.llvm.org/t/rfc-mlir-vector-deprecate-then-remove-vector-splat/87143/1
The last PR was #152230

This PR completely removes vector.splat. In addition to removing vector.splat from VectorOps.td, it

- Updates the few remaining places where vector::SplatOp is created (now vector::BroadcastOp is created)
- Removes temporary patterns where vector.splat is replaced by vector.broadcast

The only place 'vector.splat' appears is now the files

https://github.com/llvm/llvm-project/blob/main/mlir/utils/tree-sitter-mlir/test/corpus/op.txt
 and

https://github.com/llvm/llvm-project/blob/main/mlir/utils/tree-sitter-mlir/dialect/vector.js
