AYON: Tools enhancements

[iLLiCiTiT]

Changelog Description

Few enhancements and tweaks of AYON related tools.

Additional info

• Fixed typo set_name_filer to set_name_filter.
• Renamed get_current_project_name to get_selected_project_name in ProjectsCombobox.
• Hierarchy model adds more information to FolderItem (path and folder type).
• Moved universal TreeView to tool utils from workfiles tool, and use it in FoldersWidget.
• UNDERLINE_COLORS_ROLE has bigger offset to avoid clashes with FoldersWidget roles.
• Projects/Folders/Tasks widgets have more public methods and signals.

Branch of this PR will be used as base for few of my future PRs.

Testing notes:

All changes should not affect, any logic of tools. All tools loader, workfiles, launcher should work as expected.

First issue being in the Launcher that when triggering Explore Here on top folder it says Folder does not exists even tho it does...

however it works on others like
shots
shots_b3d
in my particular case and also on assets and their corresponding task

[LiborBatek]

The Focus to context btn or how to call this function btn does not work in all cases....not keeping the proper task when hit and switch to the other task type in the asset instead, it works some times but some times not. Leading user to different task type which could lead to confusion and possible mistake when triggering Save As later on.

And in Loader this Focus Context btn doesnt do anything at all...is that correct??

Good point, but that's not caused by this PR, and I don't plan to fix it in this PR. Fixed for loader. Workfiles tool needs more attention in different PR.

Completelly unrelated to this PR. Already has created issue and task.

All seems fine.
