[Codegen][Tuner] Expose XOR shuffle bounds and validation functions in CAPI (#23442)

After https://github.com/iree-org/iree/pull/23175, we now generate
swizzle hint ops for scaled gemms whose parameters are set during
`lowering_config` selection. These parameters (`rowElems` and
`accessElems`) can be chosen via the tuner too (although in the future
we intend for there to be an analytically derived solution to this).
This PR exposes two functions, `getXorShuffleBounds` and
`isXorShuffleValid`, to allow the tuner to constrain its search space
for applicable XOR swizzles.

IREE: Intermediate Representation Execution Environment

IREE (Intermediate Representation Execution Environment, pronounced as “eerie”) is an MLIR-based end-to-end compiler and runtime that lowers Machine Learning (ML) models to a unified IR that scales up to meet the needs of the datacenter and down to satisfy the constraints and special considerations of mobile and edge deployments.

See our website for project details, user guides, and instructions on building from source.
