Support `triton.language.dtype` with `torch.compile` (#121690)
Putting this PR as an RFC since I have resorted to some horrible hacks in order to make this work.
```
(Pdb) p triton.language.float32
triton.language.fp32
(Pdb) p str(triton.language.float32)
'fp32'
(Pdb) p repr(triton.language.float32)
'triton.language.fp32'
```
This means that we need to "rewrite" them for fx graph and inductor execution.
This PR allows Mamba2 to work with `torch.compile`.
