MCE view controls:

* Move controls back over to the left, as they were before. Wide images and muscle memory have been causing frustration.
* Improve the experience and unify the UI of media view controls. Audio and video views now require an initial click to select before further interaction.
* CSS clean up and organization.

There is no more `video-playlist` shortcode. To use video, it is now `[playlist type="video" ....]`. Also deleting core playlist styles. The `style` attribute is still supported, defaulting to `light`. Our core style support was 4-5 CSS rules.

Affix the audio view toolbar to the bottom as opposed to the top of the view. Otherwise it's not accessible when the view is the first item in the content. Said views keep a newline underneath, so there's space for it to appear there instead. fixes #27548, see #27320.
