<summary>Changes</summary>
This PR adds "value casting", i.e., a mechanism to wrap `ir.Value` in a proxy class that overloads dunders such as `__add__`, `__sub__`, and `__mul__` for fun and great profit.
This is thematically similar to https://github.com/llvm/llvm-project/commit/bfb1ba752655bf09b35c486f6cc9817dbedfb1bb and https://github.com/llvm/llvm-project/commit/9566ee280607d91fa2e5eca730a6765ac84dfd0f (and indeed relies on the former) but is implemented at the Python API level because
1. it's quite tough to intervene in all the places `ir.Value` is returned from the pybind code, in particular [`PyOpResultList::slice`](https://github.com/llvm/llvm-project/blob/5a600c23f9e01f58bac09a8fad096e194fc90ae2/mlir/lib/Bindings/Python/IRCore.cpp#L2303);
2. registering Python classes to be conjured up by the pybind code is fairly brittle IMHO;
3. it's always better to have things be purely in Python so they can more easily be understood/patched/monkey-patched.
This has been my secret (lol) plan for quite a while now and it wasn't possible until https://github.com/llvm/llvm-project/pull/68308 but now we've arrived.
The design looks like this:
- a `ValueCasterT` is a callable that takes an `ir.Value` (or `ir.OpResult`) and returns a subclass of `ir.Value` or `None`;
- the user registers a value caster associated with a `TypeID` (using `register_value_caster`) that is responsible for casting `ir.Value`s with a matching `type.typeid`;
- an `ir.Value` produced by a value builder will be `maybe_cast`ed, depending on whether there's a value caster registered for `ir.Value.type.typeid`
In the absence of a registered value caster, the `ir.Value` or `ir.OpResult` is just returned unscathed.
The user can optionally provide a `priority` when registering the value caster in order to allow for more/less specific proxies; for example, one might want to make attempt at wrapping a `tensor<10x10x!tt.ptr<f32>>` (a tensor of [triton pointers](https://github.com/makslevental/triton-pp/blob/main/triton_pp/dialects/ext/triton.py#L380)), which has the same `TypeID` as `RankedTensorType`, which might already have been [wrapped (possibly upstream)](https://github.com/makslevental/mlir-python-utils/blob/main/mlir/utils/dialects/ext/tensor.py#L111). Should the higher priority caster fail, it can return `None` and the next priority caster will be tried.
**Note, this doesn't affect any paths other than through the "value builders"**.
