Create a CI action to build and cache mesa on all platforms for reliability

**Context**
F3D CI currently rely on different graphical stack on each platform:
 - Linux: xvfb
 - macOS: native
 - Windows: binary mesa

Lets unify them by building and caching a specific version of mesa in order to avoid rendering inconsistencies, especially on macOS.

**Suggested solution**
 - Add mesa as a classic CI dependency
 - Use it in our CI
