[mlir] Refactor LICM into a utility

LICM is refactored into a utility that is application on any region. The implementation is moved to Transform/Utils.

[mlir][cf-sink] Accept a callback for sinking operations

(This was a TODO from the initial patch).

The control-flow sink utility accepts a callback that is used to sink an operation into a region.

[mlir][cf-sink] Accept a callback for sinking operations

(This was a TODO from the initial patch).

The control-flow sink utility accepts a callback that is used to sink an operation into a region.
The `moveIntoRegion` is called on the same operation and region that return true for `shouldMoveIntoRegion`.
The callback must preserve the dominance of the operation within the region. In the default control-flow
sink implementation, this is moving the operation to the start of the entry block.

[mlir:Transforms] Move out the remaining non-dialect independent transforms and utilities

This has been a major TODO for a very long time, and is necessary for establishing a proper
dialect-free dependency layering for the Transforms library. Code was moved to effectively
two main locations:

* Affine/
There was quite a bit of affine dialect related code in Transforms/ do to historical reasons
(of a time way into MLIR's past). The following headers were moved to:
Transforms/LoopFusionUtils.h -> Dialect/Affine/LoopFusionUtils.h
Transforms/LoopUtils.h -> Dialect/Affine/LoopUtils.h
Transforms/Utils.h -> Dialect/Affine/Utils.h

The following transforms were also moved:
AffineLoopFusion, AffinePipelineDataTransfer, LoopCoalescing

* SCF/
Only one SCF pass was in Transforms/ (likely accidentally placed here): ParallelLoopCollapsing
The SCF specific utilities in LoopUtils have been moved to SCF/Utils.h

* Misc:
mlir::moveLoopInvariantCode was also moved to LoopLikeInterface.h given
that it is a simple utility defined in terms of LoopLikeOpInterface.

[mlir] Add a ControlFlowSink pass.

Control-Flow Sink moves operations whose only uses are in conditionally-executed regions into those regions so that paths in which their results are not needed do not perform unnecessary computation.
