API Validation Tests for RenderPass StoreOp.
Test Coverage:
- Tests that when depthReadOnly is true, depthStoreOp must be 'store'.
- When depthReadOnly is true and depthStoreOp is 'discard', an error should be generated.
- Tests that when stencilReadOnly is true, stencilStoreOp must be 'store'.
- When stencilReadOnly is true and stencilStoreOp is 'discard', an error should be generated.
- Tests that the depthReadOnly value matches the stencilReadOnly value.
- When depthReadOnly does not match stencilReadOnly, an error should be generated.
- Tests that depthReadOnly and stencilReadOnly default to false.
TODO: test interactions with depthClearValue too
