subs: use correct font aspect ratio for libass + converted subs
Rendering of ASS subtitles tries to be bug compatible with VSFilter and stretches fonts when the video is anamorphic (some scripts try to compensate for this VSFilter behavior, so trying to render them "correctly" would give the wrong result). However this behavior is not appropriate for subtitles we converted to ASS format ourselves for libass rendering, as they certainly don't have VSFilter bug workarounds. Change the code to use different behavior for "native" ASS tracks and converted ones. It's questionable whether the VSFilter-compatible behavior is appropriate for external .ass files either, as there could be anamorphic and non-anamorphic versions of the same video and the bug-compatible behavior can only be correct for one alternative at most. However it's probably better to keep it as a default at least, so that extracting a muxed subtitle track and using that does not give behavior different from the original muxed one. The aspect ratio setting is per ASS_Renderer, and changing it resets libass caches. For that reason this commit adds separate renderer instances to use for the "correct" and "VSFilter bug compatible" cases.
