[1.7] Remove torch.vmap (pytorch#45571)

torch.vmap is a prototype feature and should not be in the stable
binary. This PR:
- Removes the `torch.vmap` API
- Removes the documentation entry for `torch.vmap`
- Changes the vmap tests to use an internal API instead of `torch.vmap`.

Test Plan:
- Tested locally (test_torch, test_type_hints, test_vmap), but also wait
for CI.

[jit] fix tuple alias analysis (pytorch#41992)

Previously when analyzing a TupleConstruct, we ignored the aliasing
information of the inputs and simply marked all elements of the returned
tuple as wildcards. But since we can fully reason about the contents of
a tuple statically, we should be able to assign them aliasing
information.

This analysis was not only incomplete but produced incorrect results,
since if `a` is not a wildcard, `a noalias wilcard`. So if we looked at
`tuple(a)` and reported the aliasing info as `tuple(wildcard)`, then
`tuple[0] noalias a`, which is...wrong.

scatter/gather - check that inputs are of the same dimensionality (py…

Release GIL during DDP construction. (pytorch#40877)

Summary:
Pull Request resolved: pytorch#40495

As part of debugging flaky ddp_under_dist_autograd tests, I realized
we were running into the following deadlock.

1) Rank 0 would go into DDP construction, hold GIL and wait for broadcast in
DDP construction.
2) Rank 3 is a little slower and performs an RRef fetch call before the DDP
construction.
3) The RRef fetch call is done on Rank 0 and tries to acquire GIL.
4) We now have a deadlock since Rank 0 is waiting for Rank 3 to enter the
collective and Rank 3 is waiting for Rank 0 to release GIL.

2) waitforbuildbot
