bootstrap: Verify C++14 capabilities before using them

In commit a605bf43 (Extend C++17/C++14 feature checks to cover more
standard library APIs, 2019-02-27, cpp-modules-20190312.1~52^2~1) we
added checks to the main build of CMake to verify C++14 capabilities
before using C++14 flags to build.  Add these to the bootstrap check
too.
