  -----------
  [mlir][vector] Add fold pattern to constant-fold InsertStridedSliceOp

Fold InsertStridedOp(ConstantOp into ConstantOp) -> ConstantOp.

This pattern comes with vector size threshold to make sure we do not
introduce too many large constants.

This help clean up code created by the Wide Integer Emulation pass.
