libobs: Add deinterlacing API functions Adds deinterlacing API functions. Both standard and 2x variants are supported. Deinterlacing is set via obs_source_set_deinterlace_mode and obs_source_set_deinterlace_field_order. This was implemented in to the core itself because deinterlacing should happen before effect filters are processed, but after async filters are processed. If this were added as a filter, there is the possibility that a different filter is processed before deinterlacing, which could mess with the result. It was also a bit easier to implement this way due to the fact that that deinterlacing may need to have access to the previous async frame. Effects were split in to separate files to reduce load time (especially for yadif shaders which take a significant amount of time to compile).

libobs: Simplify YUV conversion Currently several shaders need "DrawMatrix" techniques to support the possibility that the input texture is a "YUV" format. Also, "DrawMatrix" is overloaded for translation in both directions when it is written for RGB to "YUV" only. A cleaner solution is to handle "YUV" to RGB up-front as part of format conversion, and ensure only RGB inputs reach the other shaders. This is necessary to someday perform correct scale filtering without the cost of redundant "YUV" conversions per texture tap. A necessary prerequisite for this is to add conversion support for VIDEO_FORMAT_I444, and that is now in place. There was already a hack in place to cover VIDEO_FORMAT_Y800. All other "YUV" formats already have conversion functions. "DrawMatrix" has been removed from shaders that only supported "YUV" to RGB conversions. It still exists in shaders that perform RGB to "YUV" conversions, and the implementations have been sanitized accordingly.
