Rework internals of how VSE caching is done. Primarily to make all the caching logic more understandable from development point of view, but also has several user visible implications (more details in the PR): - Simpler and fewer caching UI options, - Disk cache is gone (primary reason: proxies are kinda the same thing), - VSE cache size set in preferences is actual size used for VSE caches now (previously caching stopped as soon as whole Blender used that much memory, even if some memory usage was not about VSE at all), - Certain scenarios of cache invalidation are faster now.
