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).

Converts ActivityEnter, ActivityExit, ActivityStart, ActivityStop,
ActivityPause, StartActivityTime, RequestActivityEnter,
RequestActivityExit and ShowActivityCountdown to NetGameMsgs in
ActivityMessages.{h,cpp}, switches their callers (racing, shooting
gallery, survival, waves, AG course, NT combat challenge) and deletes
the old GameMessages::Send* / HandleRequestActivityExit functions.
REQUEST_ACTIVITY_EXIT is registered in GameMessageHandler's map.
No wire change. Verified by comparing every struct byte for byte with a
frozen verbatim copy of the old functions (tests/.../Legacy) over a
grid of inputs, both to one client and as a broadcast (a temporary test
proved the copy matched production before it was deleted), plus hand
computed golden bytes, round trips and a deliberate field mutation that
made the tests fail. Layouts confirmed against the 1.10.64 client in
Ghidra. Only difference: a broadcast no longer makes
the extra Send(UNASSIGNED, false) that RakNet already rejected.
