    Message : Control Debug layers in ANGLE_platform_angle. Debug layers seem to be a universal thing among functional back-ends. D3D, OpenGL and Vulkan all need some kind of controls for debugging, so it seems to make sense to make this control part of the base extension. Default the extension to EGL_DONT_CARE, which allows the back-end to have a lot of flexibility in terms of implementation. Also enable the extension in the D3D11 and OpenGL back-ends, and set the extension to enabled for angle_end2end_tests. Remove EGLVulkanEXTTest since it no longer tests anything not tested in the base ANGLETest class.
