Title: Make autoprefixer browsers fixed

Lets make the browsers we support through autoprefixer fixed, so we can control when we don't want to support specific browsers anymore and avoid issues like in #13792.

For the browsers which weren't explicitly set I used the oldest version that wouldn't cause new prefixes to be added as a baseline.
