This patch implements tile and fuse transformation for ops that
implement the tiling interface. To do so,
- `TilingInterface` needs a new method that generates a tiled
implementation of the operation based on the tile of the result
needed.
- A pattern is added that replaces a `tensor.extract_slice` whose
source is defined by an operation that implements the
`TilingInterface` with a tiled implementation that produces the
extracted slice in-place (using the method added to
`TilingInterface`).
- A pattern is added that takes a sequence of operations that
implement the `TilingInterface` (for now `LinalgOp`s), tiles the
consumer, and greedily fuses its producers iteratively.
