[PATCH] wined3d: Use extensions present in Apple core contexts to detect Apple OpenGL.

[Chip Davis]

Core contexts on Mac OS don't have GL_APPLE_fence or
GL_APPLE_ycbcr_422... but they do have GL_APPLE_flush_render and
GL_APPLE_rgb_422. So, go back to using APPLE_flush_render in our OS X
detection, and accept APPLE_rgb_422 in addition to APPLE_ycbcr_422.
