The MediaViewer and MultimediaViewer* instruments were disabled circa
October 2021 in Ie7dd8739efc.
This patch removes those instruments and any supporting code and data.
Notably, this patch does not remove the mw.mmv.logging.ViewLogger
instrument, which is responsible for logging image views.

Results in small UI changes, but allows us to delete a lot
of code duplication.

Really, why should this be forbidden? These onclick handlers do waaaaay
to much. They do not only block what they should block, they block way
more stuff, like resizing the textarea and interacting with it in any
way that involves the mouse. This is not the intention of this code.
I'm sorry to say that, but this code is the equivalent of "disable
right click to prevent stealing images" on 1990s web pages. Please,
please let's not do this. Let the user do what he expectes and is used
to do.
