Upstream Actor::CalculateLOS with IDs/offsets from hdtSMP64

## Request Upstream the `Actor::CalculateLOS` reverse-engineered function (currently hand-defined in hdtSMP64) to CommonLibVR/CommonLibSSE-NG. ## Background hdtSMP64 currently defines this function manually via a `REL::Relocation`: ```cpp // NiAVObject* Actor::CalculateLOS_1405FD2C0(Actor *aActor, NiPoint3 *aTargetPosition, NiPoint3 *aRayHitPosition, float aViewCone) // Used to raycast from the actor to a world position. Returns non-null if something is hit along the ray. // Pass 2π to aViewCone to ignore the actor's LOS cone. typedef RE::NiAVObject* (*_Actor_CalculateLOS)(RE::Actor* aActor, RE::NiPoint3* aTargetPosition, RE::NiPoint3* aRayHitPosition, float aViewCone); REL::Relocation<_Actor_CalculateLOS> Actor_CalculateLOS{ REL::VariantID(36754, 37770, 0x0605B10) }; // SE ID: 36754 | AE ID: 37770 | VR offset: 0x0605B10 ``` Note: `CalculateLOSLocation` (the adjacent function) is already present in CommonLibVR, but `CalculateLOS` (the raycast-to-world-position variant) is not. ## Reference - PR: https://github.com/DaymareOn/hdtSMP64/pull/238 - Comment: https://github.com/DaymareOn/hdtSMP64/pull/238#discussion_r2990680484 - Requested by: @alandtse
