ts-reset for DOM lib

[lifeiscontent]

Hey @mattpocock, thanks for ts-reset. I've been thinking about making something similar for DOM specs. Several APIs say they exist, but they do not work across all browsers.

My plan on how to solve this is to use something like Playwright, inspect all DOM APIs and check that they exist and write a JSON object out towards the end of the test runner and then make a diff and where the APIs don't work across browser make the API optional, and append some docs with notes around which browsers support what.

What do you think about this being a part of or an extension of ts-reset?
