Remap CDC and MSC endpoints to share physical endpoint numbers. This change separates IN/OUT directional states for RP2 endpoints to prevent cross-talk, ensures SAMD21 and SAMD51 endpoint configuration merging does not overwrite bidirectionally shared registers, implements missing SAMD endpoint stall and clear methods, and corrects SAMD interrupt loop bounds to iterate over physical endpoint numbers rather than dynamic configuration entries.
