Update descriptor set with image binding.

Parameters

descriptor_set_id	ID of descriptor set to update
binding	Binding index within the descriptor set
image_view	Vulkan image view to bind
sampler	Vulkan sampler to bind
layout	Image layout (default: eShaderReadOnlyOptimal)
array_element	Array index for array bindings (default: 0)
