External Libraries: Update jQuery to 1.12.4-pre.

This version includes a fix for the media library which didn't open under certain conditions. The issue was tracked upstream as "Specific table CSS style breaks `.is(':visible')`", see https://github.com/jquery/jquery/issues/3065.
Also fixed: "Element which is not in page is still :visible in IE8", see https://github.com/jquery/jquery/issues/3043.

Changelog: https://github.com/jquery/jquery/compare/1.12.3...376caf4d

See #36533.
