[1.11] Remove torch.vmap (#65496) (#72275)
* release 1.11 Install torch from test channel, Pin builder and xla repo (#72217)
* [1.11] Remove torch.vmap (#65496)
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_autograd, test_type_hints, test_vmap),
but also wait for CI.
