This runs dawn_end2end_tests both with/without use_tint_generator on Vulkan, OpenGL, and OpenGL ES backends. This is a temporary solution until we add an dawn_end2end_use_tint_generator_tests suite in the bot configuration after all backends can support use_tint_generator or have the appropriate test suppressions.
