Implementing part of design outlined in #126087. - VSE thumbnail cache has a new implementation, hopefully simpler and easier to understand. - Instead of cache key being a VSE strip, frame index, plus complicated logic for cache items linking etc., - The cache is keyed by media file path (if multiple strips use the same input file, they will share cache entries), frame index within media file, and any extra data (e.g. steam index for multi-steam videos) - Much reduced cache flickering and strange/weird thumbnail choices. - Likewise, thumbnails no longer disappear-and-reload on operations like Undo, dragging new video strip into timeline, or F12 render. - Thumbnails now load faster. - Images use dedicated/faster thumbnail loading routines when a format can do that (e.g. JPG and EXR can). - Movies reuse ffmpeg decoding context for neighboring strips that use the same file (as often happens when cutting footage) - Thumbnail requests are processed on several threads now too. Images and more detail in PR. Pull Request: https://projects.blender.org/blender/blender/pulls/126405
