debug: add milestone logging, identify LoadWeaponSprites message pump

Found root cause of intermittent crashes: DDGame__LoadWeaponSprites
(0x5717A0) is a loading tick function that pumps the Windows message
loop (uses QueryPerformanceCounter + message dispatch). During this
pump, WM_TIMER/WM_PAINT handlers run game task code that reads DDGame
fields — if any field is still null, it crashes.

The original C++ constructor sets fields in an order compatible with
whatever the message pump reads. Our Rust version must match that
exact order, OR defer the loading tick calls until all critical fields
are initialized.

This is also why DSSound_LoadEffectWAVs (which calls LoadWeaponSprites
between each WAV) must have wrapper passed correctly — it too pumps
messages.
