Enhance Model Loading By Providing Parallelism, Uses Optional Env Flag (#36835)
* Get parallel loader working. Include tests.

* Update the tests for parallel loading

* Rename env variables.

* Add docs for parallel model weight loading.

* Touch up parallel model loading docs.

* Touch up parallel model loading docs again.

* Edit comment in test_modeling_utils_parallel_loading.py

* Make sure HF_PARALLEL_LOADING_WORKERS is spelled correctly in modeling_utils.py

* Correct times for parallelized loading, previous times were for a "hot" filesystem

* Update parallel model loading so the spawn method is encapsulated. DRY up the code by leveraging get_submodule.

* Update docs on model loading parallelism so that details on setting the multiprocessing start method are removed, now that the package handles this step internally.

* Fix style on model loading parallelism changes.

* Merge latest version of master's modeling_utils.

* Removed unused variable.

* Fix argument packing for the parallel loader.

* Fix state dict being undefined in the parallel model loader.

* Rename variables used in parallel model loading for clarity. Use get_module_from_name().

* Switch to the use of threads for parallel model loading.

* Update docs for parallel loading.

* Remove the use of json.loads when evaluating HF_ENABLE_PARALLEL_LOADING. Prefer simple casting.

* Move parallelized shard loading into its own function.

* Remove use of is_true(). Favor checking env var true values for HF_ENABLE_PARALLEL_LOADING.

* Update copyright to 2025 in readme for paralell model loading.

* Remove garbage collection line in load_shard_file, implicit garbage collection already occurs.

* Run formatter on modeling_utils.py

* Apply style fixes

* Delete tests/utils/test_modeling_utils_parallel_loading.py
