mpv: Overhaul selection of shader-based scalers

Browse source 
This removes ravu-zoom and ravu-lite in favour of standard ravu. It also
adds more nnedi3 shaders with neurons between 2^4 and 2^8, each with a
window size of 8x4. This should give a wide range of options that work
on all machines and still give acceptable results (at least balanced to
the performance).

The reason for this switch is ravu’s subpar performance, since it often
produces more artifacts than it avoids.

It also avoids some code duplication at the cost of making it more
complex.
