fix(ci+cpp): OffsetFinder SolutionDir resolution and ARM64 PCH overrides

- build-and-release.yml: build RDPWrapOffsetFinder via .sln target so
  \ resolves to the submodule root (src-csharp/RDPOffsetFinder/)
  where zydis/ lives; building the vcxproj directly sets SolutionDir to the
  vcxproj folder causing C1083 on all include and lib paths
- RDPWrap.vcxproj: add missing Release|ARM64 overrides on stdafx.cpp
  (PrecompiledHeader=Create) and dllmain.cpp (empty, disables PCH) so
  the ARM64 DLL build does not fail with C1083 missing .pch
