misc NPC natives and FCNPC parity

[Knogle]

This adds a batch of missing FCNPC NPC natives and callbacks on the server side.

Added callbacks:

- OnNPCUpdate
- OnNPCChangeHeightPos
- OnNPCStreamIn
- OnNPCStreamOut
- OnNPCVehicleEntryComplete
- OnNPCVehicleExitComplete
- OnNPCVehicleTakeDamage

Added functions:

- NPC_SetQuaternion
- NPC_GiveQuaternion
- NPC_GetQuaternion
- NPC_GivePos
- NPC_GiveFacingAngle
- NPC_GiveHealth
- NPC_GiveArmour
- NPC_GiveAmmo
- NPC_GiveAmmoInClip
- NPC_GiveVelocity
- NPC_GiveSurfingOffsets
- NPC_GetClosestEntityInBetween
- NPC_SetPlaybackPath
- NPC_GetPlaybackPath
- NPC_SetWeaponInfo
- NPC_GetWeaponInfo
- NPC_SetWeaponDefaultInfo
- NPC_GetWeaponDefaultInfo
- NPC_SetMoveMode
- NPC_GetMoveMode
- NPC_SetMinHeightPosCall
- NPC_GetMinHeightPosCall
- NPC_ShowInTabListForPlayer
- NPC_HideInTabListForPlayer

This also adds the matching SDK exposure and keeps move mode documented as compatibility surface only where a real MapAndreas / ColAndreas backed implementation does not exist yet. For this case we have to consider some way to natively have Z data available for the server.

I've done the testing using the NPC test gamemode from @itsneufox https://github.com/itsneufox/NPC-bare-test-omp-gamemode

I compeletely don't understand the point in NPC_Give* functions. Why we should inflate main API with basically one-liner functions which could be done on Pawn side in some wrapper. The rest is kinda good for me 👍

Ahoy, i've added those in order to match the function set provided by FCNPC, to be sort of a drop-in replacement.
