Subdivided the new icons in 3 size categories. As requested by UX
Used the company naming scheme for uniformity and easy recognition.
Known issues:
- Top/Bottom category wasn't taken into account by UX at the time. Since
this is a recent addition. Both the Walls and Top/Bottom will be updated.
- Cloud/Network connection icons 12px don't render correctly. Due to the
theme-ing.
- Extruder Icons do not render correctly.
CURA-8010_new_icons
The material is added multiple times to the variant nodes, and overwriting it with the eventual right one was going wrong.
This does not solve it entirely (because the less specific one still ends up selected _initially_ because it gets added first, and the order can't be guaranteed.
part of CURA-6863
We just track it via the preference value itself rather than duplicating that in any other data structure. It's simple enough.

We can reuse our duplicateMaterial function again but in a simpler way. Also finding the preferred material is simpler with our container tree.
However there seems to be a problem with finding the preferred material; it's not finding generic_pla for UM3 and AA0.4 anyway, and then falls back on a random material. This needs to be fixed in the variant node class.

Just like MaterialManager used to be. There can be only one instance of the page then.
This prevents a crash when Qt deletes the QObject because it's no longer used in the page when you close the preferences screen. But when you open it again it doesn't construct a new one. Now there is always one instance so that's not a problem any more. Also it allows other pages to access this item.

Just like the QualityManagementModel, this class is intended to be used as proxy for the material management page in the preferences. I'm intending to move all relevant pyqtSlots from the material manager into this one. The advantage of this switch is that the material manager had no well-bounded scope and so tended to become a big mess of all sorts of functions. This one has a clear scope: serve as a proxy for the buttons you can press in the preferences screen for materials.

The onActiveMaterialChanged signal is triggered upon loading a material for the first time. This is hard to fix without breaking stuff, so we will revert this part.
This re-introduces a bug where if you change a material diameter such that the material disappears from the list, it is still selected and you can change its properties in the details panel.
