David Ormsbee 8b17afc818 fix: prefer HTML5 video when youtube support is deprecated.
In the case where a server/course has both:

* YouTube deprecated (waffle flag: videos.deprecate_youtube = True)
* HLS enabled (ConfigModel: HLSPlaybackEnabledFlag, in video_config)

Prior to this commit, we would prefer the HLS source if one of the
HTML5 video sources specified a .m3u8 file. However it looks like this
file isn't always guaranteed to be produced.

This fix always prefers HTML5 video sources to YouTube if the server or
course is configured to deprecate YouTube, as long as at least one
non-YouTube source is found. TNL-8594.

Note that this may confuse users because we're essentially bypassing
their Studio-specified preferred primary source with a server-wide
setting.

Status: Deprecated (DEPR-24)

Responsibilities
================
XModules render specific course run content types to users for both authoring and learning. For instance, there is an XModule for Videos, another for HTML snippets, and another for Sequences. This package provides both the implementations of these XModules as well as some supporting utilities.

Direction: Convert and Extract
==============================
XModule exists today as a complex set of compatibility shims on top of XBlock (all XModules currently inherit from XBlock). The goal is for all XModules to either be converted into pure XBlocks or be deleted altogether. Extracting them into separate repositories would be ideal, but even just converting them to pure XBlocks would significantly simplify the runtime.
