In the `try_compile` source file signature we propagate the caller's value of `CMAKE_<LANG>_FLAGS` into the test project. Extend this to propagate `CMAKE_<LANG>_FLAGS_<CONFIG>` too instead of always using the default value in the test project. This will be useful, for example, to allow the MSVC runtime library to be changed (e.g. `-MDd` => `-MTd`). However, some projects may currently depend on this not being done, so we need to activate the behavior using a policy. This change was originally made by commit v3.6.0-rc1~160^2 (try_compile: Honor CMAKE_<LANG>_FLAGS_<CONFIG> changes, 2016-04-11) but without the policy and so had to be reverted during the 3.6 release candidate cycle. Fixes #16174.
