Fix some errors affecting the Web editor

- Don't warn about minimized/maximized modes not being available.
- Blender and FBX export both depend on running thirdparty applications,
  which can't be done (easily at least) for Web and Android editors.
- Editor theme complained about not being able to retrieve texture data
  for an icon. It was only used once so instead of flipping at runtime,
  let's just add a flipped icon.

Part of #65702.
