[ISSUE-9451] Loadout Management

[FenikSRT4]

Fixes PathOfBuildingCommunity/PathOfBuilding#9451

Description of the problem being solved:

• Adds Loadout management replacing the single New Loadout option in the loadout dropdown. This new Manage option opens a ListControl menu for creating new, copying, renaming and deleting whole loadouts. This does not change the rules around managing the names for each set that's part of a loadout. For example, renaming an item set still disassociate the loadout.
• Multiple functions that existed in the list controls were refactored to be functions that were part of the respective tab class. ie: Renaming is now a function in ItemsTab as a class function instead of that logic living in the list control
• Several refactors around builds were pulled out of creating the list into functions so they could be reused or called elsewhere.
• This now implements a new type of functionality for mixing and matching loadout properties, named New/Copy Custom. This dialog allows users to select properties from the list of properties for the respective type to copy into a new loadout, or create the property from new. ex: ItemSet from Loadout 1, SkillSet from Loadout 2, Passive Tree from Loadout 3, and a New Config Set.
