This is on top of #2225. The goal is to be able to skip specific tests. Many core test sets have just one test that uses subprocess or threads. Others have a few tests that are failing due to upstream problems in emscripten. I went through and switched to skipping specific tests in as many cases as I could. In modules where most or all tests use threading or subprocess, I gave up and put a comment saying something like 35/50 tests fork and I didn't want to bother to salvage the remaining ones.

In order to accommodate using patterns to skip specific tests (and also extra comments) I switched the format of `python_tests` to a yaml file. This gives us significantly more flexibility in the structure of the file and allows us to use `ruamel.yaml` to update it. We gain a lot flexibility while reducing the length of `make_test_lists.py` modestly from 108 to 78 loc.

In the future, hopefully we should be able to make fixes by deleting one skip pattern and looking into why that particular test fails.
