[mlir,python] Expose replaceAllUsesExcept to Python bindings (#115850)

Problem originally described in [the forums
here](https://discourse.llvm.org/t/mlir-python-expose-replaceallusesexcept/83068/1).

Using the MLIR Python bindings, the method
[`replaceAllUsesWith`](https://mlir.llvm.org/doxygen/classmlir_1_1Value.html#ac56b0fdb6246bcf7fa1805ba0eb71aa2)
for `Value` is exposed, e.g.,

```python
orig_value.replace_all_uses_with(
    new_value               
)
```

However, in my use-case I am separating a block into multiple blocks, so
thus want to exclude certain Operations from having their Values
replaced (since I want them to diverge).

Within Value, we have
[`replaceAllUsesExcept`](https://mlir.llvm.org/doxygen/classmlir_1_1Value.html#a9ec8d5c61f8a6aada4062f609372cce4),
where we can pass the Operations which should be skipped.

This is not currently exposed in the Python bindings: this PR fixes
this. Adds `replace_all_uses_except`, which works with individual
Operations, and lists of Operations.
