Refactor dependencies to expose Vector transformations as patterns - NFC

This CL refactors some of the MLIR vector dependencies to allow decoupling VectorOps, vector analysis, vector transformations and vector conversions from each other.
This makes the system more modular and allows extracting VectorToVector into VectorTransforms that do not depend on vector conversions.

This refactoring exhibited a bunch of cyclic library dependencies that have been cleaned up.
