For now it can only be binary failed/succeeded

Trying workaround https://forum.godotengine.org/t/how-to-detect-shader-compilation-errors-at-runtime/66687 by injecting a random uniform bool <name>; and - to prevent the uniform to get optimized away - <name>; in the fragment shader code.
If the uniform isn't found in Filesystem.shader.get_shader_uniform_list(), the shader most probably wasn't compiled correctly.

-> This naive approach works, but without a detailed error message
