Support team vs team format

This is an intermediate step for other official formats like Archenemy (#2038), Two Headed Giant (#349) or even [Horde Magic](https://mtg.gamepedia.com/Horde_Magic) (excellent format for xMage).

That format like current free for all but players can attack-select only another team members. If all team members die -- game win. Many cards have wrong implementation and need to fix (example [Pulse Of The Grid](https://github.com/magefree/mage/blob/ba50812eb4ffbd45755888c02bc6fea03c217a28/Mage.Sets/src/mage/cards/p/PulseOfTheGrid.java) implementation with `game.getState().getPlayersInRange()` which return all other players, not team).

As idea: mark players as "not opponent" flag -- it can help to filter players in effects.

Start with the team-versus-team behavior described in the issue and inspect Mage.Sets/src/mage/cards/p/PulseOfTheGrid.java, especially its use of game.getState().getPlayersInRange(). Review issues #2038 and #349 for related official formats. Done means team membership is respected when selecting attack targets and the game ends when all members of a team die.
