Add a rating request for Elo+Glicko format-specific data

Browse Source 
This can be used as backing to implement placements matchmaking. Placements mechanism are a discrete mechanism, while Glicko-2 provides the data required as a continuum.

See PR thread, shut down prematurely due to supposed technical infeasibility.

https://www.smogon.com/forums/threads/placement-matchmaking-to-preventing-ladder-smurfing.3751632/

My initial intent is to keep the ladder points and sorting Elo-based (with all its current mechanisms, 1000 floor and decay), but move matchmaking to Glicko-2.

Matchmaking would get a new requirement: candidate players must be both below XOR above an arbitrary RPRD threshold (this can well match the current "provisional" rating threshold, which is 100).
