Don't run test/autograd/test_fallback.py in parallel (#106866)
Fixes https://github.com/pytorch/pytorch/issues/106754
This PR:
- moves test/autograd/test_fallback.py to test_autograd_fallback.py and
removes it from test_autograd.py (necessary for the next step)
- adds test_autograd_fallback.py to parallel test blocklist.
- lintrunner really wanted to make changes to the files, but other than
that, it is a move.
The problem is that we set a global option (the autograd fallback mode)
during these tests which may cause the tests to interfere with each
other.
Test Plan:
- python test/run_test.py -i test_autograd_fallback
NOTE to diff train oncall:
- You'll also need to modify the test/autograd/test_fallback.py TARGET in
caffe2/test/TARGETS since we renamed the file.
