Add a basic ActorSheetV2 implementation which provides a starting place for modules that wish to use the ApplicationV2 framework for Actor sheet UI.

Create the base implementation for ActorSheetV2, for package developers to base their new AppV2 Actor sheets from.

To get feature parity with ApplicationV1 the following should be included:

• [ ] Drag & Drop support for ActiveEffect, Actor, Item & Folder.
  • [ ] ActiveEffect Creation.
  • [ ] Actor exists but doesn't execute any logic.
  • [ ] Item Creation & Sorting.
  • [ ] Folders with type Item create all items inside of it as owned items.
• [ ] Add items and effects properties to _prepareContext for access in templates.
• [ ] Add 'Configure Token' button to header bar.
• [ ] Remove actor.overrides during _prepareSubmitData

getter for token too

Thought: I think this is a good opportunity to introduce what D&D has been doing, which is disable fields affected by actor.overrides since otherwise the input could be misleading.

Also, a ticket that's related to possible Drag & Drop handling: https://github.com/foundryvtt/foundryvtt/issues/10372

I've implemented something basic for now (all there was time for). Several of the requests in this issue were below the line but can be added later. At least foundry.applications.sheets.ActorSheetV2 is now available to be used in a standardized way.
