options: refactor how --opengl-dcomposition is declared

vo_opengl used to have it as sub-option, which made it very hard to pass
down option values to backends in a generic way (even if these options
were completely backend-specific). For --opengl-dcomposition we used a
VOFLAG to deal with this. Fortunately, sub-options are gone, and we can
just add it as global option.

Move the option to context_angle.c and add it as global option. I
thought about adding a mechanism to let backends declare options, which
would get magically picked up my m_config instead of having to add them
to the global option list manually (similar to VO vo_driver.options),
but decided against this complexity just for 1 or 2 backends. Likewise,
it could have been added as a single option to avoid the boilerplate of
an option struct, but then again there are probably going to be more
angle suboptions, and it's cleaner.
