[mlir][vector] Add Vector-dialect interleave-to-shuffle pattern, enable in VectorToSPIRV (#92012)
This is the second attempt at merging #91800, which bounced due to a
linker error apparently caused by an undeclared dependency.
`MLIRVectorToSPIRV` needed to depend on `MLIRVectorTransforms`. In fact
that was a preexisting issue already flagged by the tool in
https://discourse.llvm.org/t/ninja-can-now-check-for-missing-cmake-dependencies-on-generated-files/74344.
Context: https://github.com/iree-org/iree/issues/17346.
Test IREE integrate showing it's fixing the problem it's intended to
fix, i.e. it allows IREE to drop its local revert of
https://github.com/llvm/llvm-project/pull/89131:
https://github.com/iree-org/iree/pull/17359
This is added to VectorToSPIRV because SPIRV doesn't currently handle
`vector.interleave` (see motivating context above).
This is limited to 1D, non-scalable vectors.

[mlir][VectorOps] Add unrolling for n-D vector.interleave ops (#80967)
This unrolls n-D vector.interleave ops like:
```mlir
vector.interleave %i, %j : vector<6x3xf32>
```
To a sequence of 1-D operations:
```mlir
%i_0 = vector.extract %i[0]
%j_0 = vector.extract %j[0]
%res_0 = vector.interleave %i_0, %j_0 : vector<3xf32>
vector.insert %res_0, %result[0] :
// ... repeated x6
```
The 1-D operations can then be directly lowered to LLVM.
Depends on: #80966
