This commit migrates the font tests away from the bots. Not only are the font tests broken on the Windows bot since some time, they also run on Python 2 (end of life since January 2020) and `ttx` 3.19.0 (released in November 2017). The latter is installed via a submodule, which requires more complicated logic for finding and running `ttx`. We solve the issues by implementing a modern workflow that installs the most recent stable Python and `ttx` (`fonttools` package) versions. This simplifies the `ttx` driver code as well because it can now assume `ttx` is available on the path (just like we do for e.g. `node` invocations). GitHub Actions takes care of creating a virtual environment with `fonttools` in it so that the `ttx` entrypoint is available. Locally the font tests can be run in a similar way by creating and sourcing a virtual environment with `fonttools` in it before running the font tests, and a README file is included with instructions for doing so.
