Add support role to tutorial

I can't stand the amount of people who get auto-filled into support then proceed to do nothing because they don't know how to support the mode should essentially be a whole different practice tool, and unlocking all support champs for use.

this practice mode should include: -healing and shielding (clutch heals) -body blocking (for example braum should be unlocked here to demonstrate usage of his shield) -Instructing builds (situations etc.)

This probably require a lot of work, and would probably still get ignored by players, but at least it's (could be) worth the effort or could potentially fix some issues regarding "fresh" ranked players.
