Use JIT Plug-in for coverage to cover JIT'd functions and methods (#56310)
Summary:
This PR is step 2 (after https://github.com/pytorch/pytorch/issues/56708) to having JIT coverage--it actually uses the plug-in in CI!
Disclaimer: note that this will mark the entire JIT'd function/method as covered without seeking proof that the
compiled code has been executed. This means that even if the code chunk is merely compiled and not run, it will get
marked as covered.
Pull Request resolved: https://github.com/pytorch/pytorch/pull/56310
Test Plan:
We should see coverage improvements in CI after. A file to look out for would be `torch/jit/quantized.py`, which should have more coverage after this PR, which it does!

More generally, the whole jit folder got ~3% increase in coverage, I believe.
