Ref #70924
This addresses part 1 of the issue, allowing `torch.squeeze` to be
passed a tuple of dimensions. e.g.
```python
x.squeeze(0).squeeze(0)
```
can now be written
```python
x.squeeze((0, 1))
```
(assuming x has at least 2 dimensions)

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.
The PR fixes https://github.com/pytorch/pytorch/issues/90833

- `torch.enable_check_sparse_tensor_invariants` and `torch.is_check_sparse_tensor_invariants_enabled` functions to globally enable/disable the invariant checks and to retrieve the state of the feature, respectively

Fixes#91107
Added `softmax` docs in
- `pytorch/torch/_tensor_docs.py`
- `pytorch/torch/_torch_docs.py `
- `pytorch/docs/XXX.rst` files. Here XXX represents all those files where I made the change
Although I have added `softmax` in `docs` directory, I was not sure which files/folders required the edits so there could be issues

The documentation of `torch.rand` was missing the `generator` keyword argument in the function signature. However, the argument is explained in the documentation and `torch.rand` accepts that argument.
