[Move] Full Stuff cheeks implementation

[geeilhan]

What are the changes the user will see?

Stuff Cheeks is now fully implemented. (#3503)

What are the changes from a developer perspective?

Added a new class MoveSelectCondition inside move.ts which checks if a move is selectable in the move menu. It contains the condition (UserMoveConditionFunc) that allows selecting a move.

StuffCheeksCondition extends MoveSelectCondition and contains the condition that fails if the user does not hold at least 1 berry. If the condition fails a StuffCheeksTag, which extends MoveRestrictionTag, is added. This tag gets removed at the end of the turn.

Also added
private selectableConditions: MoveSelectCondition[] = [];
which saves the condition for the move.

Currently working on refactoring this so I use BattlerTags (MoveRestricitonBattlerTag) instead of making the move directly unselectable

I think something is wrong with the tests. npm run test doesn't work after syncing with beta branch
