Vulkan: Add robust init for NULL texture image. In gl::ReadPixels(), ValidateReadPixels() will try to flush staged updates before readPixels. In the case where a texture was initialized with null RGBA data, no Framebuffer dirty bits are set, and thus the staged clear would never be flushed from the staged updates. 1. Add robust init in TextureVk::initImage to ensure image is initialized. Test: ./angle_end2end_tests --gtest_filter=\ RobustResourceInitTest*_Vulkan_AllocateNonZeroMemory 2. Update stageSubresourceRobustClear() to kEmulatedInitColorValue in the case where robust resource was initialized without full RGBA format to update init value of robust resource. Test: texture-attachment-formats.html in webgl_conformance_vulkan_passthrough_tests. 3. Revert "Suppress Vulkan RobustResourceInit tests." Revert commit a8e6a463121b9920564fb6efd7f2c857d7023fe3. Reason for revert: re-enable related robust tests.
