servo: Merge #12578 - Document Windows installation hacks (from larsbergstrom:windows_deps); r=metajack

<!-- Please describe your changes on the following line: -->
This is based on the awesome work by @UK992 in #12573.

Basically, it downgrades GCC on Windows to 5.4 within the mingw environment. This is a stopgap until #11756 is completed and we no longer need mingw.

Fixes #12512
