.circleci: Downgrade CUDA 11.2 -> 11.1

[seemethere]

There were performance issues with 11.2 so we're opting to build
packages for 11.1 instead

Follow up to #3341

Relates to pytorch/pytorch#52151

Looks like we're experiencing failures on windows builds:

For wheels (CircleCI logs):

pytorch/pytorch#52503 should fix this.

@fmassa @seemethere Do we need to fix the cmake scripts as well? cc @janeyx99
Fix: #3419

[janeyx99]

I had merged pytorch/pytorch#52305 intending to introduce a dummy torch_cuda when we split the library, which might resolve these downstream dependencies. However, it's not cherrypicked into the release cut :/ so it probably would be best to go with your fixes here @peterjc123
