Image Plane: Add support for EEVEE

Browse Source 
- Fixes incorrect handling of incompatible engines. There is a global list of compatible
  engines, but `create_cycles_material` didn't use it, displaying an incorrect warning
  when using the operator.
- Add `BLENDER_EEVEE_NEXT` to compatible engines.
- Remove `BLENDER_EEVEE` from compatible engines.
- Add render method option. This replaces the material `blend_method`
- Remove material blend method option (replaced by `render_method`)
- Remove material shadow option. Not needed anymore as shadows use
  the node tree for evaluation.

**TODO**
- Manual should still be updated. Will be done after this patch lands.
- I did some basic tests. I am not familiar with this operator, but think it
  should handle all the different cases. Would be nice to have some
  render tests for this to detect regressions.
