Fixes for BGSAIWorldLocationRefRadius & LODDistance

[frakkin64]

I am not sure how to test these two fixes specifically, but the module compiles and runs in game with OG/AE.

BGSAIWorldLocationRefRadius (AdModuleBGSAIWorldLocationRefRadius.cpp)

• rsi is the address of the NiPointer<TESObjectREFR>&.
• Since rsi is a reference, test rsi, rsi checks the wrong thing.
• The check is now cmp qword[rsi], 0, which tests the _ptr.

LODDistance (AdModuleLODDistance.cpp)

• NG/AE: the 1-byte 0xEB patch moves from REL::ID(2197513)+0x5B to REL::ID(2213411)+0x64. REL::ID(2197513)+0x5B is BGSMod::Attachment::Mod::GetFilterChance. REL::ID(2213411)+0x64 is the visibility lambda in BGSDistantObjectBlock::UpdateInstanceVisibility.
• OG: REL::Offset(0x52A80) (xor eax,eax; ret) is replaced with REL::ID(1425899), so it resolves through Address Library. The old RVA was in the middle of BGSMod and was a getter, the new one is SetVisibleDistant. This aligns OG to what the NG/AE patch was doing.

ThisVirtualCall (5-arg overload) (Core/AdUtils.h)

• The call passed a4 twice (a1, a2, a3, a4, a4, a5), so a5 landed in the wrong slot.
• It now passes a1..a5 once each.
• This overloaded form is not used currently.
