Add fallbacks and mention non-working features when using Compatibility

- Make 3D lights with shadows darker when using Compatibility to better
  match the apperance of Forward+/Mobile, due to the use of sRGB blending
  for those lights.
- Silence some warnings when running projects with the Compatibility
  rendering method, such as the one about 2D MSAA not being supported.
- Rebake lightmaps in Global Illumination to improve quality and reduce
  light leaking with improvements from 4.3.
  - Increase probe density for dynamic objects, and mark the moving box
    as a dynamic object for GI purposes.

This is done to improve the experience with the web-based demos,
which always run with the Compatibility rendering method.
