feat: Use CMAKE_MSVC_RUNTIME_LIBRARY for runtime selection in MSVC(#1198)

Previously, when BUILD_SHARED_LIBS was set to FALSE (OFF), the runtime library was
forcibly set to MultiThreaded. This commit replaces that behavior by using the
CMAKE_MSVC_RUNTIME_LIBRARY option, allowing users to select between MultiThreaded
and MultiThreadedDLL as a build option.
