gallium: put video-related enums in separate header

The forward references to video enum types in p_context.h causes
a massive number of compiler warnings (ISO C forbids forward references
to ‘enum’ types).

By putting the new video enums in a separate header that can be included
by p_context.h and p_screen.h we can avoid this.
