UBO consolidation

[alexcristici]

UBOs was reorganized for all shaders. As a convention: drawableUBO contains the matrix, interpolations and other parameters that are used only in vertex shader.
UBOs that were bound per drawable (like drawableUBO or tilePropsUBO) are now consolidated in a vector per layer instance and bound per layer. The UBOs are consolidated for Metal and Vulkan backends.
Uniform blocks were removed, they are not used anymore because UBOs are bound in the layer where there is no access to shader informations. So now there are some reserved UBO slots for vertex or fragment binding only.
