GL_ARB_map_buffer_range is not supported

I found in adapter_gl.c a note
~~~
        /* GL_ARB_map_buffer_range and GL_APPLE_flush_buffer_range provide the
same
        * functionality. Prefer the ARB extension */
~~~
and then check with glxinfo.
Yes, I have no GL_ARB_map_buffer_range and I have GL_APPLE_flush_buffer_range.
This is macOS!

So there is a simple solution:
- if GL_APPLE_flush_buffer_range is supported then report to game that
GL_ARB_map_buffer_range is supported too.
- but we have not to use GL_ARB_map_buffer_range and use
GL_APPLE_flush_buffer_range when possible.

I know, this is macOS specific change and I am not sure if it reliable for
linux. May be it will be better to use conditions like
#ifdef _apple_
