Dynamic light loop in PBR Shader

[SiebenCorgie]

Its better to have a somewhat dynamic light loop in the shader like this:

 for (uint i = 0U; i < min(MAX_LIGHTS, u_NumLights); ++i) {
}

(taken from here: https://github.com/three-rs/three/blob/master/data/shaders/pbr_ps.glsl )

Has also been fixed, the shader gets a new struct:

layout(set = 3, binding = 3) uniform LightCount{
  uint points;
  uint directionals;
  uint spots;
}u_light_count;

which holds the number of lights, the loops then decide which is smaller, the max count or the light count per type.
