This PR introduces a device_assert op to trigger device-side assertions within torch.compile. This implementation is based on the suggestion in [this comment](https://github.com/pytorch/pytorch/issues/147282#issuecomment-2756056084).
Changes Included
- Implemented device_assert op and overrides has_side_effect to return True to avoid removal by dead code elimination.
- Commented out the assert_async_msg_decomp and functional_assert_async_msg_decomp decompositions to disable the default assert decomposition inside Inductor.
- Added lowering for torch.ops.aten._assert_async.msg to convert assert calls into the ops_handler.
- Implemented the codegen method for the device_assert op. This supports generating C++ and Triton code.
- Added test cases to verify both "should throw" and "should not throw" scenarios.
Fixes#147282
