  Implement EGL_EXT_surface_compression
  
  This patch adds implementation of EGL_EXT_surface_compression to
  ANGLE, including new API eglQuerySupportedCompressionRatesEXT and
  adding EGL_SURFACE_COMPRESSION_EXT in EGLQuerySurface and
  EGLCreateWindowSurface/EGLCreatePlatformWindowSurface.
  Angle end2end test is added to verify the extension.
