When presenting WebVR on insecure sites, a warning needs to be presented to the user. This change renders these messages on textures to be added to a GL scene.

- Text is rendered with gfx::Canvas and gfx::RenderText, previously disabled for android.
- Fallback fonts were handled with Skia's font manager.
- The text is measured before rendering in order to layout properly, reducing empty space.
- The icons are positioned on the right on RTL languages.
