options, subs: add --ass-vsfilter-aspect-compat
Add option --ass-vsfilter-aspect-compat and corresponding property ass_vsfilter_aspect_compat. The setting controls whether to enable the emulation of traditional VSFilter behavior where subtitles are stretched if the video is anamorphic (previously always enabled for native SSA/ASS subtitles). Enabled by default. Add 'V' as a new default keybinding to toggle the property.
