Redundant exception types in `except (PermissionError, OSError):`. Write `except OSError:`, which catches exactly the same exceptions.
https://github.com/pytorch/pytorch/actions/runs/13935844871/job/39141062991
When hipify files, or writing cprofile files, PermissionError is not enough when the file is located in a place that is not writable at all, or other OS errors happened when writing files.
This fix makes the code more robust.

* Automatically applies ruff rule 401. Turns loops into equivalent list comprehensions which are faster and do not leak the scope of the loop variables.
* list comprehensions not only often have better typing, but are 50+% faster than for loops on overhead. They also preserve length information etc and are better for the interpreter to optimize.
* Manually went back and made mypy happy after the change.
* Also fixed style lints in files covered by flake8 but not by pyfmt

Summary:
AMD lowering duration is 1.55x longer than H100. Profiling shows hipification related functions took 22% of overall lowering time.
This diff cuts that time by safely memoize the trie to regex logic. The trick is to incrementally build a state of the trie during the trie construction. The state is the hash of all the words added to the trie.

This change modifies the `hipify_python.py` script to properly detect all directories, `include` and `ignore` paths during hipification process on Windows, by changing the path syntax convention to a UNIX-like one.
Since in many places the script assumes a UNIX-like convention by using paths with forward slashes `/`, I decided to accommodate for it by converting Windows paths to UNIX-like ones. By doing it so, the number of changes to the file is limited. Moreover this early-on unification allows for the rest of the code to have a battle-tested linux-like behaviour.
Another option would be to use `Path` object from `pathlib` to represent all paths in the script, however, it would impact a broader share of a code and would hence require a more meticulous evaluation in terms of non-altered logic and edge cases.

This updates ruff to 0.285 which is faster, better, and have fixes a bunch of false negatives with regards to fstrings.
I also enabled RUF017 which looks for accidental quadratic list summation. Luckily, seems like there are no instances of it in our codebase, so enabling it so that it stays like that. :)

- BatchLinearAlgebraLib.cpp is now split into one additional file
- BatchLinearAlgebraLib.cpp uses only cusolver APIs
- BatchLinearAlgebraLibBlas.cpp uses only cublas APIs
- hipify operates at the file level and cannot mix cusolver and cublas APIs within the same file
- cmake changes to link against hipblas instead of rocblas
- hipify mappings changes to map cublas -> hipblas instead of rocblas

This PR fixes the circular issue during hipification process by introducing current_state to track whether a file is processed for hipification. (Iterative DFS)
The issue arises when two header files try to include themselves, which leads to a circular recursion or an infinite loop.

This PR is the first step towards refactors the build for nvfuser in order to have the coegen being a standalone library.
Contents inside this PR:
1. nvfuser code base has been moved to `./nvfuser`, from `./torch/csrc/jit/codegen/cuda/`, except for registration code for integration (interface.h/interface.cpp)
2. splits the build system so nvfuser is generating its own `.so` files. Currently there are:
- `libnvfuser_codegen.so`, which contains the integration, codegen and runtime system of nvfuser
- `nvfuser.so`, which is nvfuser's python API via pybind. Python frontend is now exposed via `nvfuser._C.XXX` instead of `torch._C._nvfuser`
3. nvfuser cpp tests is currently being compiled into `nvfuser_tests`
4. cmake is refactored so that:
- nvfuser now has its own `CMakeLists.txt`, which is under `torch/csrc/jit/codegen/cuda/`.
- nvfuser backend code is not compiled inside `libtorch_cuda_xxx` any more
- nvfuser is added as a subdirectory under `./CMakeLists.txt` at the very end after torch is built.
- since nvfuser has dependency on torch, the registration of nvfuser at runtime is done via dlopen (`at::DynamicLibrary`). This avoids circular dependency in cmake, which will be a nightmare to handle. For details, look at `torch/csrc/jit/codegen/cuda/interface.cpp::LoadingNvfuserLibrary`
Future work that's scoped in following PR:
- Currently since nvfuser codegen has dependency on torch, we need to refactor that out so we can move nvfuser into a submodule and not rely on dlopen to load the library. @malfet
- Since we moved nvfuser into a cmake build, we effectively disabled bazel build for nvfuser. This could impact internal workload at Meta, so we need to put support back. cc'ing @vors

### Description
Enables jiterator for ROCm builds. This includes necessary porting when hiprtc and nvrtc behavior differed. This also ported ROCm versus CUDA differences w.r.t. MAX_DIMS and NUM_THREADS from the non-jiterator code paths into jiterator.
### Testing
CI with ciflow/trunk label to force running ROCm workflows that are currently trunk-only.

This Diff improves `hipify_python`, which is needed for AMD GPUs.
Change 1:
```
if (c == "," or ind == len(kernel_string) - 1) and closure == 0:
```
This is needed to deal with the following case (ex: https://github.com/pytorch/pytorch/blob/master/aten/src/ATen/test/cuda_vectorized_test.cu#L111)
```
kernel<<<val, func()>>>(...)
// In this case, kernel_string is "val, func()"
// so closure gets 0 when ind == len(kernel_string) - 1.
```
Change 2:
```
mask_comments()
```
This is needed to deal with a case where "<<<" is included in a comment or a string literal (ex: https://github.com/pytorch/pytorch/blob/master/torch/csrc/deploy/interpreter/builtin_registry.cpp#L71)
```
abc = "<<<XYZ>>>"
// Though this <<<XYZ>>> is irrelevant to CUDA kernels,
// the current script attempts to hipify this and fails.
```
Test Plan:
This patch fixes errors I encountered by running
```
python3 tools/amd_build/build_amd.py
```
I confirmed, with Linux `diff`, that this patch does not change HIP code that was generated successfully with the original script.

Pull Request resolved: https://github.com/pytorch/pytorch/pull/67323
Applied patch proposed by Jeff https://github.com/pytorch/pytorch/pull/63948#issuecomment-952166982.
In PyTorch, we map cuBLAS->rocBLAS and cuSPARSE->hipSPARSE. Note the prefix, roc versus hip.
The 'hip' APIs offer a more direct CUDA-friendly mapping, but calling rocBLAS directly has better performance.
Unfortunately, the `roc*` types and `hip*` types differ, i.e., `rocblas_float_complex` versus `hipComplex`.
In the case of SPARSE, we must use the hip types for complex instead of the roc types,
but the pytorch mappings assume roc. Therefore, we create a new SPARSE mapping that has a higher priority.
Its mappings will trigger first, and only when a miss occurs will the lower-priority pytorch mapping take place.
When a file contains "sparse" in the filename, a mapping marked with API_SPARSE is preferred over other choices.
