I applied some flake8 fixes and enabled checking for them in the linter. I also enabled some checks for my previous comprehensions PR.
This is a follow up to #94323 where I enable the flake8 checkers for the fixes I made and fix a few more of them.

Follow-up of #89582 to drop flags like `CUDA11OrLater` in tests. Note that in some places it appears that `TEST_WITH_ROCM` is _implicitly_ guarded against via the `CUDA11OrLater` version check, based on my best-guess of how `torch.version.cuda` would behave in ROCM builds, so I've added `not TEST_WITH_ROCM` in cases where ROCM wasn't previously explicitly allowed.

This PR is a copy of https://github.com/pytorch/pytorch/pull/90849 that merge was reverted.
The PR adds "check sparse tensor invariants" flag to Context that when enabled will trigger sparse tensor data invariants checks in unsafe methods of constructing sparse COO/CSR/CSC/BSR/BSC tensors. The feature includes the following changes to UI:
`torch.sparse.check_sparse_tensor_invariants` class provides different ways to enable/disable the invariant checking.
`torch.sparse_coo/csr/csc/bsr/bsc/compressed_tensor` functions have a new optional argument `check_invariants` to enable/disable the invariant checks explicitly. When the `check_invariants` argument is specified, the global state of the feature is temporarily overridden.

Reverted https://github.com/pytorch/pytorch/pull/90463 on behalf of https://github.com/ZainRizvi due to This is causing test failures: FAILED inductor/test_torchinductor_opinfo.py::TestInductorOpInfoCUDA::test_comprehensive_linalg_pinv_singular_cuda_float64 - RuntimeError: unexpected success linalg.pinv.singular, torch.float64, cuda
This PR extends the `Tensor.to_sparse()` method to `Tensor.to_sparse(layout=None, blocksize=None)` in a BC manner (`layout=None` means `layout=torch.sparse_coo`).
In addition, the PR adds support for the following conversions:
- non-hybrid/hybrid COO tensor to CSR or CSC or a COO tensor
- short, bool, byte, char, bfloat16, int, long, half CSR tensor to a BSR tensor
and fixes the following conversions:
- hybrid COO to COO tensor
- non-batch/batch hybrid BSR to BSR or BSC tensor

A longstanding confusion in the implementation of fake tensor and proxy tensor is what to do about torch.ops.aten.sym_sizes and related calls. In particular, when you have a tensor that (1) has symbolic shapes and (2) has a `__torch_dispatch__` call, previously, you would always get `__torch_dispatch__` calls for sizes/strides query, *even if you didn't request it* via the dispatch kwargs in `make_wrapper_subclass`.
The reason for this is because we were previously mixing several concepts: "I want to dispatch to Python", "I want to call a virtual method" and "I have dynamic shapes". A single boolean variable controlled all of these things, and so it was not possible to understand inside TensorImpl what the user had actually originally requested.
In this PR, we track each of these concepts individually so that we can preserve user intent. Then, we combine these into a single "policy" variable that controls whether or not we can use the fastpath or not. For the policy to trigger, we only need one of the exceptional cases to be true.
Billing of changes:
* Rename `set_sizes_strides_policy` to `set_custom_sizes_strides`; in general, you cannot DIRECTLY set policy; you have to indirectly set it by the public functions.
* Some helpers for sizes and strides, since it's more complicated (as it is an enum, rather than just bools as is the case for device and layout). `matches_python_custom` is used to test the Python dispatch user ask. `matches_policy` does the policy test (only used in the user facing functions.)
* I reorged the accessor methods so that they are more logical. This makes the diff bad, so I recommend reading the final code directly.
* The default custom implementations now more reliably call their default() implementations
* As bonus refactor, I devirtualized some functions that don't need to be virtual
* `set_sym_sizes_and_strides` is renamed to `set_sizes_and_strides` to make it easier to use in template contexts; it optionally takes a storage offset now so you can set all three values at the same time. If you use the SymInt overload but there are no symbolic integers, we give you a normal resize.
* This adds `sym_storage_offset` since we had that in the symbolic shapes branch and there's no reason not to put it in (and it reduces merge conflicts)

Previously, we would trace through the following with no error:
```
from torch.fx.experimental.proxy_tensor import make_fx
import torch
def f(x, y):
return x[0, y:]
```
Even though the output shape is dependent on the data of `y`. Now, throw on the conversion of `y` to an integer.
It would be nice to not break on constant tensors but I'll do that as the next PR (Edit: done with https://github.com/pytorch/pytorch/pull/84387). Sketching out how that would work (and keep in mind this is applicable Dynamo tracing and not just AOT Autograd)
I think to do that you would need to :
- hold strong refs to a set of constant tensors, and only allow them to be captured from `lift_fresh.copy`
- when you run a mutable op, either remove it from the set of constant tensors or run the operator for real
- limit to small constant tensors
Anything else ?
