  [mlir][Transforms] Add a PadTilingInterface transformation and hook i… (#144991)

…t up to the transform dialect

This revision revisits the padding transformation from first principles
and prepares it to work more generally with TilingInterface.

Compared to structured.transform.pad it has the following differences:
- no support for nofold, copy-back, transpose and hoisting: these have
been carried by the padding op in the very early days of StructuredOps
and have since then been separated out as independent transformations
that compose.
- no conflated static bounding box derivation attempts:
pad_tiling_interface composes more naturally with or without tiling.
- properly derives padding size on outputs where multiple dimensions
contribute: this is not supported in structured.transform.pad
- geared towards supporting TilingInterface once the proper control
mechanisms are supported through a PadSizeComputationFunction (supports
LinalgOp by default)

This will gradually replace structured.transform.pad as it is fleshed
out and tested more comprehensively.

In the future this should be moved out of a specific Linalg
implementation file and into a more general "Structured" file.
