  [mlir] Add ScalableVectorType and FixedVectorType (#87986)

This PR adds two small convenience Vector types:

  * `ScalableVectorType` and `FixedVectorType`.

The goal of these new types is two-fold:
  * Enable idiomatic checks like `isa<ScalableVectorType>(...)`.
  * Make the split into "Scalable" and "Fixed-wdith" vectors a bit more
    explicit and more visible in the code-base.


The new types are added in mlir/include/mlir/IR (instead of e.g.
mlir/include/mlir/Dialect/Vector) so that the new types can be used
without requiring any new dependency (e.g. on the Vector dialect).
