Subject: Hard-code some try_compile results for third-party libraries

Our bundled third-party libraries perform many `try_compile` checks for
compatibility with their upstream build systems.  For many of the checks
we already know the result for compilers we support for building CMake
itself, especially on Windows.  Hard-code known results to avoid running
the checks.
