`getTiledImplementation`/`generateResultTileValue` only computes the tiled operation, but does not insert the result into any tensor.

the op.
While The tiling interface provides a mechanism for operations to be
tiled into tiled version of the op (or another op at the same level of
abstraction), the `generateScalarImplementation` method added here is
the "exit point" after all transformations have been done. Ops that
implement this method are expected to generate IR that are directly
lowerable to backend dialects like LLVM or SPIR-V dialects.

While most of methods in ViewLikeInterface accept an `OpFoldResult` for
the offset/size/stride that may be static, represented as `Attribute`,
or dynamic, represented as `Value`, the `Range` abstraction only
accepted `Values`. This can often lead to known-constant
offset/size/strides being materialized into constant operations and
hinder further constant propagation without explicitly running the
constant folding pass. This often leads to a more complicated than
necessary addressing code being emitted. Switch `Range` to use
`OpFoldResult`. Code that uses `Range` currently keeps materializing the
constants to minimize the effect of this change on the IR. Further
commits will make use of this.

`TileConsumerAndFuseProducersUsingSCFForOp`
Replace iterators of the outermost loop with region arguments of the innermost
one. The changes avoid later `bufferization` passes to insert allocation within
the body of the innermost loop.

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.

implement TilingInterface for Linalg ops.
This patch adds support for tiling operations that implement the
TilingInterface.
- It separates the loop constructs that are used to iterate over tile
from the implementation of the tiling itself. For example, the use
of destructive updates is more related to use of scf.for for
iterating over tiles that are tensors.
- To test the transformation, TilingInterface is implemented for
LinalgOps. The separation of the looping constructs used from the
implementation of tile code generation greatly simplifies the
latter.
- The implementation of TilingInterface for LinalgOp is kept as an
external model for now till this approach can be fully flushed out
to replace the existing tiling + fusion approaches in Linalg.
