refactor: racing and vehicle game messages as structs

Browse Source 
Converts the 12 racing / vehicle / modular assembly messages DLU sends
and the 8 it receives to NetGameMsgs in RacingMessages.{h,cpp}, adds
eRacingClientNotificationType for NotifyRacingClient's event type,
switches the callers (RacingControlComponent, CarBoostBehavior,
PossessorComponent, slash commands), registers the received messages
in GameMessageHandler's map and deletes the old functions. Handlers are
copied verbatim. Also moves the byte-equality test helpers into a
shared GameMessageTestUtils.h.

No wire change. Verified byte for byte against a frozen verbatim copy
of the old functions over an input grid, to one client and broadcast;
received messages compared with the old handlers' read sequences
(including all 16 optional-field combinations of
VehicleNotifyHitImaginationServer) and every truncated payload
rejected; hand computed golden bytes; round trips; a deliberate field
mutation made the tests fail. Layouts confirmed against the 1.10.64
client in Ghidra. Malformed received messages are
dropped (see the foundations commit).
