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 'clear', an error should be generated.

  - Tests that when stencilReadOnly is true, stencilStoreOp must be 'store'.
    - When stencilReadOnly is true and stencilStoreOp is 'clear', 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 depthLoadValue too
