  EGL: Add support for EGL_KHR_gl_colorspace extension
  
  If the Vulkan backend supports VK_EXT_swapchain_colorspace extension,
  enable the option for applications to create surfaces with non-linear
  formats. Not all formats have non-linear versions and is platform
  specific.
  
  Tests: dEQP-EGL.functional.wide_color.*
         angle_deqp_egl_tests --use-angle=vulkan --deqp-gl-context-type=egl --deqp-case=dEQP-EGL.functional.wide_color.*
