Bug 1734649 - Part 4. Lift some conditions preventing WebGL OOP. r=jgilbert

Browse Source 
Now that WebGL runs on the Renderer thread in the compositor process
when OOP, we can now lift the threadsafe condition on Linux preventing
WebGL OOP. Regardless of webgl.out-of-process's setting, we should
always prefer by default to run worker WebGL contexts OOP to avoid
similar threadsafe conflicts in the content process.
