  Log Message:
  -----------
  [mlir][Vector] Introduce UnrollVectorOptions to control vector unrolling.

The current pattern for vector unrolling takes the native shape to
unroll to at pattern instantiation time, but the native shape might
defer based on the types of the operand. Introduce a
UnrollVectorOptions struct which allows for using a function that will
return the native shape based on the operation. Move other options of
unrolling like `filterConstraints` into this struct.
