…e Messages RCS Adds full support for RCS phone verification and consent flows used by Google Messages: * ConstellationService + Impl for phone number verification (UPI/TS.43 + Google backend fallback) * AsterismService + Impl for RCS consent * Ts43Client for carrier EAP-AKA entitlement * GoogleConstellationClient + RPC + protos for server-side verification * Phenotype flag overrides to enable UPI and disable attestation checks for Messages * RcsCallerPolicy and dedicated service registrations * Improved phone number extraction from requests This allows Google Messages to successfully provision and use RCS on microG (no root required). See microg#2994
