In various places we try to override the default mw-ui-icon behaviours
The hacks need to be removed as part of addressing the core problem.
Changes:
* Wherever we use mw-ui-icon-before in PHP - wrap the label with a span
so that label font-size is altered where needed - not the icon
* Where a small icon is needed us isSmall parameter for the Icon component
* Apply font-size to labels of mw-ui-icon-before elements
* The browser tests need a slight update to access the span element inside
a menu item - in the case of the logout button the label is always hidden,
so we need to check the visibility of the parent element (secondary_action)

Slide the main menu over the page instead of sliding the page over the
menu. Also, use viewport units for the main and notification menus.
Note, this lays foundation work for T225213.
