Tweak default SDFGI settings for better quality

- Enable Read Sky Light to get proper outdoors lighting out of the box.
- Set bounce feedback to 0.5 by default to get a better quality result.
  - Higher values may cause infinite feedback with bright surfaces.
- Increase the number of frames to converge to improve quality
  at the cost of latency. Most scenes are fairly static after all.
- Use 75% Y scale by default as most scenes are not highly vertical.

- Reorder the Y scale enum to go from the lowest Y scale to the highest.
  Also rename the "Disabled" setting to "100%" for clarity.

 			If [code]true[/code], renders [VoxelGI] and SDFGI ([member Environment.sdfgi_enabled]) buffers at halved resolution (e.g. 960×540 when the viewport size is 1920×1080). This improves performance significantly when VoxelGI or SDFGI is enabled, at the cost of artifacts that may be visible on polygon edges. The loss in quality becomes less noticeable as the viewport resolution increases. [LightmapGI] rendering is not affected by this setting.
 			[b]Note:[/b] This property is only read when the project starts. To set half-resolution GI at run-time, call [method RenderingServer.gi_set_use_half_resolution] instead.
