Adds the possibility of having a little number on top of icons.
At the moment this is used for:
* Outliner
* Node Editor bread-crumb
* Node Group node header
For the outliner there is almost no functional change. It is mostly a refactor
to handle the indicators as part of the icon shader instead of the outliner
draw code. (note that this was already recently changed in a5d3b648e3).
The difference is that now we use rounded border rectangle instead of
circles, and we can go up to 999 elements.
So for the outliner this shows the number of collapsed elements of a
certain type (e.g., mesh objects inside a collapsed collection).
For the node editors is being used to show the use count for the data-block.
This is important for the node editor, so users know whether the node-group
they are editing (or are about to edit) is used elsewhere. This is
particularly important when the Node Options are hidden, which is the
default for node groups appended from the asset libraries.

Note: This can be easily enabled for ID templates which can then be part
of T84669. It just need to call UI_but_icon_indicator_number_set in the
function template_add_button_search_menu.

Special thanks Clément Foucault for the help figuring out the shader,
Julian Eisel for the help navigating the UI code, and Pablo Vazquez for
the collaboration in this design solution.
