FindBoost: Add checks for component-specific headers
This supplements the existing library checks, to cater for the possibility that the libraries are present but the headers are not. This can happen when the Boost collections is split up into multiple packages and not all are installed, and will avoid the checks silently passing when the build would subsequently fail.
