Update the Chipset struct to follow the `IsaVersion` definition from llvm's `TargetParser`. This is a follow up to https://github.com/llvm/llvm-project/pull/106169#discussion_r1733955012. * Add the stepping version. Note: This may break downstream code that compares against the minor version directly. * Use comparisons with full Chipset version where possible. Note that we can't use the code in `TargetParser` directly because the chipset utility is outside of `mlir/Target` that re-exports llvm's target library.
