* Fix warnings/errors on MSVC 1. update googletest to tag release-1.11.0 to make googletest and googlemock compile on MSVC2022. 2. set gtest_force_shared_crt to ON in test cmake project to make tests compile on MSVC. 3. add /wd4251 and /wd4275 to MSVC compile flags to ignore DLL related warnings for class exports. 4. fix some other warnings and errors while compiling on MSVC2022.
