Rework compilation options surrounding usage of C++14 and running clang-tidy on Windows with clang-cl

There are a number of issues with running clang-tidy under Windows with clang-cl; this issue addresses those issues.
Also, -Wno-unused-lambda-capture only needs to be used when not using C++14 since there are now conditional compilation directives that use explicit lambda captures which make the warning unnecessary when using C++14 - when Boost.Stacktrace is enabled.
