vo_gpu: opengl: reduce versions in mpgl_preferred_gl_versions

Currently mpv requires a bare minimum of GL 2.1, although it tries to
use 3.2+ core contexts when possible.

The GLX and EGL spec effectively guarantee that the implementation will
give you the highest compatible version possible. In other words:

Requesting 3.2 core profile will always give you core profile and the
version will be in the 3.2 .. 4.6 range - as supported by the drivers.

Similarly for 2.1 - implementation will give you either:
 - 2.1 .. 3.1, or
 - 3.2 .. 4.6 compat profile

This has been verified against the Mesa drivers (i965, iris, swrast) and
Nvidia binary drivers.

As such, drop the list to 320, 210 and terminating 0.

v2:
 - mpgl_preferred_gl_versions -> mpgl_min_required_gl_versions
 - update ^^ comment
