[mlir][Vector] Support efficient shape cast lowering for n-D vectors (#123497)
This PR implements a generalization of the existing more efficient
lowering of shape casts from 2-D to 1D and 1-D to 2-D vectors. This
significantly reduces code size and generates more performant code for
n-D shape casts that make their way to LLVM/SPIR-V.

[mlir][vector] add result type to vector.extract assembly format (#66499)
The vector.extract assembly format currently only contains the source
type, for example:
%1 = vector.extract %0[1] : v
[mlir][vector] add result type to vector.extract assembly format (#66499)
The vector.extract assembly format currently only contains the source
type, for example:
%1 = vector.extract %0[1] : vector<3x7x8xf32>
it's not immediately obvious if this is the source or result type. This
patch improves the assembly format to make this clearer, so the above
becomes:
%1 = vector.extract %0[1] : vector<7x8xf32> from vector<3x7x8xf32>

[mlir][VectorOps] Add lowering for vector.shape_cast of scalable vectors
This adds a lowering similar to the general shape_cast lowering, but
instead moves elements a (scalable) subvector at a time
[mlir][VectorOps] Add lowering for vector.shape_cast of scalable vectors
This adds a lowering similar to the general shape_cast lowering, but
instead moves elements a (scalable) subvector at a time via
vector.scalable.extract/insert. It is restricted to the case where both
the source and result vector types have a single trailing scalable
dimension (due to limitations of the insert/extract ops).
The current lowerings are now disabled for scalable vectors, as they
produce incorrect results at runtime (due to assuming a fixed number
of elements).
Examples of casts that now work:
// Flattening:
%v = vector.shape_cast %arg0 : vector<4x[8]xi8> to vector<[32]xi8>
// Un-flattening:
%v = vector.shape_cast %arg0 : vector<[8]xi32> to vector<2x1x[4]xi32>

Vector dialect patterns have grown enormously in the past year to a point where they are now impenetrable.
Start reorganizing them towards finer-grain
