DisplayVk: Always expose EGL_KHR_gl_colorspace. In the case of the sRGB color space the VK_EXT_swapchain_colorspace is actually not required to create a swap chain. The requirement should be lowered and VK_KHR_get_surface_capabilities2 should be used to enumerate if the color spaces from VK_EXT_swapchain_colorspace are available.
