GPU: Create Info for GPU_SHADER_2D_IMAGE_MULTI_RECT_COLOR.

This patch converts GPU_SHADER_2D_IMAGE_MULTI_RECT_COLOR shader to use
the GPUShaderCreateInfo pattern. It can be used as a reference when
converting other shaders.

In this special case the flat uniform vector cannot be used anymore as it
doesn't fit as push constants. To solve this a uniform buffer is used.
