This adds a static is_viable() method to all rasterizers which has to be called before initializing the rasterizer. This allows us to check what rasterizer to use in OS::initialize together with the GL context initialization. This commit also adds a new project setting "rendering/quality/driver/driver_fallback" which allows the creator of a project to specify whether or not fallback to GLES2 is allowed. This setting is ignored for the editor so the editor will always open even if the project itself cannot run. This will hopefully reduce confusion for users downloading projects from the internet. We also no longer crash when GLES3 is not functioning on a platform. This fixes #15324
