[LLVM Integrate] Bump llvm, torch-mlir, stablehlo (#48)

[LLVM](https://github.com/llvm/llvm-project/tree/e5ed7b6e2fd368b722b6359556cd0125881e7638)
(Feb 27)

[StableHlo](https://github.com/openxla/stablehlo/tree/d214e2e2bd568a80a9f25515907b64dd7b98c538)
(March 5)**

[Torch-MLIR](https://github.com/llvm/torch-mlir/tree/a86e89ecb5c7929a39a38743fb7cacadf1ff41bb)
(Mar 4)


DONE:
- [x] **This is the stablehlo commit right before Bazel 7 (bzlmod)
changes landed (openxla/stablehlo#2006) which
breaks downstream integrations. Stablehlo devs have kindly provided a
fix at openxla/stablehlo#2009 - if it works,
I'll revise the stablehlo commit to HEAD.
