rhi: Allow testing QRhiRenderPassDescriptors for compatibility
For Metal and Vulkan this needs actual work because that's where
the concept of renderpass descriptors is relevant. GL and D3D can
just return true always.
The big benefit of this is that Qt Quick can now compare renderpass
descriptors via isCompatible() for its pipeline cache (similarly to
how it is already using isLayoutCompatible() for srbs), and so
renderpass descriptors for layers (Item.layer, ShaderEffect) will
typically be compatible and so can pick up pipelines created by other
layers from the cache.
Also add autotests for shader resource binding and renderpass descriptor
compatibility.
