build: set MSVC-related cmake policies to new

Setting cmake policies CMP0091 and CMP0092 to new are much essential for smooth building with MSVC. CMP0091 sets the runtime flags in a consistent, defined manner. This is extremely important as you can't use two different runtime libraries on MSVC and will lead to build failure. CMP0092 makes it possible to set the warning level. For dependencies we completely silence all warnings. More information on these policies: https://cmake.org/cmake/help/latest/policy/CMP0091.html https://cmake.org/cmake/help/latest/policy/CMP0092.html
