Commit 5a8923ef95 removed support for legacy status icons from
the notification system, as we no longer want them to appear as
notifications. As we are unfortunately not quite at a point where
we can remove all support for them for good, so we now need an
alternative place to put them. Add a small dedicated tray at the
bottom which appears when any legacy status icons are active. By
default it is almost completely hidden to not interfere with the
user's windows, but can be expanded on demand to interact with
the icons.

GNOME Shell throws the following warning message:
'St-WARNING **: Too many values for border-radius property.'
Was fixed with just remove the last '0' on the 'border-radius'
property in the '.tile-preview-left.on-primary' class on both files:
gnome-shell.css and gnome-shell-high-contrast.css.

This used to be the style-class for status icons (i.e. icon-only
top bar items). It got unused a while ago when the class used
by status icons stopped using it - except for the keyboard indicator,
which set the class manually to appear as status icon despite not
being a real icon.
Now that the button highlight is provided by the .panel-button class
on a parent, the obsolete class results in a double border on the
keyboard indicator when active - just drop it from there as well
to fix.
So we can style it differently than :hover.
We already have a active state for the menu items which includes
more than hover. For example, when the keyboard focus moves to a item
or we select programatically a item.
For this reason we need a style class named active for the meaning we
give to it in menu items, and a pseudo class active with the meaning
CSS has.

Since widnows decorations with round corners has a special shape,
which when scaled we can't match with a simple border-radius.
So to prevent to show a gap between the caption border and the
caption itself, apply a shadow.
