Projects use `try_compile` to check if they will be able to compile some particular source code. When a language standard variable like `CMAKE_CXX_STANDARD` is set, then the project intends to compile source code using a compiler mode for that standard. Therefore it makes sense for `try_compile` to use that standard in the test project too. Unfortunately this was not done when support for the `CMAKE_CXX_STANDARD` variable was first implemented. Add a policy to introduce the improved behavior in a compatible way. Closes: #16456
