  -----------
  [mlir][tensor] Apply `InsertSliceOfTransferWriteOpFolder` only when `transfer_write` overwrites all elements of `insert_slice` (#108803)

Resolves #101708

The updated logic now correctly checks if `transfer_write` completely
overwrites `insert_slice` and only then applies the rewrite for this
pattern.

This check currently covers static sizes, for dynamic sizes
value bounds analysis is needed (see `TODO:`).
