Subject: 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.
