Fixes#112633
Fixed errors relating to pydocstyle in the following files. The remaining errors are not covered in this issue. `torch/utils/dlpack.py` was not modified as the errors are relating to the function signature in the first line in the docstring which must be maintained as is for proper Sphinx interpretation.

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. :)

Introduction of api for optimizing non forward functions for mobile. As of this diff, all functions that you say to optimize will be preserved, and those functions will be run through canonical optimization. The intention is to stack each further optimization onto separate diffs since they touch multiple files, and it seems like it'd be a nightmare to review.

torch.utils.mobile_optimizer.optimize_for_mobile(net, methods_to_optimize=["forward", "foo"]) runs fine
torch.utils.mobile_optimizer.optimize_for_mobile(net, methods_to_optimize={"foo"}) optimizes just foo if the model doesnt define forward otherwise optimizes foo and forward

A previous change added the possibility of more functions being generated when bundled inputs are attached. Want to preserve those here in optimize_for_mobile
ghstack-source-id: 120862718
Test Plan:
Created a dummy model. Augment several methods with bundled inputs. Call optimize for mobile. Verified the functions are still there.
Discovered a weird interaction between freeze_module and bundled inputs. If the user does something like
inputs =[<inputs>]
augment_many_model_functions_with_bundled_inputs(
model,
inputs={
model.forward : inputs,
model.foo : inputs,
}
)
to attach their bundled inputs, freeze_module within optimize_for_mobile will error out. Instead the user would need to do something like
inputs =[<inputs>]
inputs2 =[<inputs>] # Nominally the same as the the inputs above
augment_many_model_functions_with_bundled_inputs(
model,
inputs={
model.forward : inputs,
model.foo : inputs2,

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/51153
Enabled bundled inputs for all public functions that the user wants in a torchscript module. An important caveat here is that you cant add bundled inputs to functions that were in the nn.module but weren't caught in the scripting/tracing process that brought the model to torchscript.
Old Api is exactly the same. Still only works on forward, return types the same, etc.
-----------New API-------------
Attachment of inputs:
***augment_model_with_bundled_inputs*** : works the same as before but added the option to specify an info dictionary.
***augment_many_model_functions_with_bundled_inputs*** : Similar to the above function but allows the user to specify a Dict[Callable, List[<inputs>]] (mapping function references to the bundled inputs for that function) to attach bundled inputs to many functions
Consumption of inputs:
***get_all_bundled_inputs_for_<function_name>()*** : Works exactly like get_all_bundled_inputs does, but can be used for functions other then forward if you know ahead of time what they are called, and if they have bundled inputs.
***get_bundled_inputs_functions_and_info()*** : This is easily the hackiest function. Returns a Dict['str', 'str'] mapping function_names to get_all_bundled_inputs_for_<function_name>. A user can then execute the functions specified in the values with something like
all_info = model.get_bundled_inputs_functions_and_info()
for func_name in all_info.keys():
input_func_name = all_info[func_name]['get_inputs_function_name'][0]
func_to_run = getattr(loaded, input_func_name)
The reason its done this way is because torchscript doesn't support 'Any' type yet meaning I can't return the bundled inputs directly because they could be different types for each function. Torchscript also doesn't support callable so I can't return a function reference directly either.
ghstack-source-id: 120768561
Test Plan:
Got a model into torchscript using the available methods that I'm aware of (tracing, scripting, old scripting method). Not really sure how tracing brings in functions that arent in the forward call path though. Attached bundled inputs and info to them successfully. Changes to TorchTest.py on all but the last version of this diff (where it will be/is removed for land) illustrate what I did to test.

Pull Request resolved: https://github.com/pytorch/pytorch/pull/49170
Added an extra step to **always** preserve the bundled inputs methods if they are present in the input module.
Also added a check to see if all the methods in the `preseved_methods` exist. If not, we will now throw an exception. This can hopefully stop hard-to-debug inputs from getting into downstream functions.
~~Add an optional argument `preserve_bundled_inputs_methods=False` to the `optimize_for_mobile` function. If set to be True, the function will now add three additional functions related with bundled inputs to be preserved: `get_all_bundled_inputs`, `get_num_bundled_inputs` and `run_on_bundled_input`.~~
