vo_gpu{,_next}: convert scale options to type choice

Browse Source 
This allows Tab completing them in the console and zsh, and using cycle
scale.

jinc is also added to --tscale=help's output, while before it was
missing because validate_scaler_opt() skipped filter windows with the
same name as a filter kernel, but the jinc kernel was skipped with
--tscale because it is polar.
