Include the Material Symbols fonts

[Dokug]

As Google does not seem to be updating the "Material Icons" fonts anymore and recommends switching to the "Material Symbols" fonts (as can be seen here), I would suggest adding the Material Symbols font either as a separate project or as an addition to the already existing UraniumUI.MaterialIcons project.

I can try to put together a PR for a seperate UraniumUI.MaterialSymbols project, if you'd want me to.
The Material Symbols fonts can be found here.

That makes sense, We can create another assembly for this symbols to prevent breaking changed for the current ones. I can be named as UraniumUI.Icons.MaterialSymbols and Icons library will be deprecated

@Dokug @enisn Is there a way to make use of the UraniumUI.Icons.MaterialSymbols using the Filled style?

[Dokug]

Currently I don't think so.
I would need to look into that, but I think the "filled" style is a separate font.
