[#4060] Add teleport activity

[Kapuzenjoe]

I used the opportunity to turn the new Foundry API from foundryvtt/foundryvtt#13935, specifically token.planMovement, into a dedicated activity type for #4060

Functionally, activating the activity lets the user drag the token to the desired destination. After the move is completed, the token returns to its default movement mode.

Feel free to rate the implementation. I tried to stick as closely as possible to the standard system.

Just a bit of clean up for the sheet but otherwise its looking good to me.

A few thoughts for future improvement to make things clearer when planning the teleport:

• Display icon underneath or outline around token to be teleported
• Add some way to cancel planned movement
• Add UI to indicate movement being planned like discussed in #6796 for placements

A cancel option should be fairly easy to add. Maybe with an active listener on canvas.app.view.oncontextmenu so a right-click cancels the currently planned teleport (similar for placing Tokens).

What kind of icon/outline did you have in mind? Maybe something like in Crucible where the selection frame rotates around the token while it's marked for teleportation?

Nice feature. I will get this merged into 6.0 and we can tackle any follow-up later.

For (1) we should hook into the turn marker machinery. We can pick some suitable asset to use here.

For (2) I observed that simply deselecting the controlled token is enough to cancel the teleport, which is good enough for now I think.

I also added the useRange property as I have to imagine that the targeting range will be the same as the teleport range most of the time (notable exceptions like Misty Step notwithstanding).
