Check doxygen output in travis (#11124)

Summary:
This PR adds a .travis.yml check for our C++ documentation. The goal is to avoid any documentation/comments in our C++ code that would break the doxygen output and possibly ruin the C++ documentation site (currently https://pytorch.org/cppdocs).

For this, we:
1. Run doxygen and record any warnings,
2. Filter out some known bogus warnings,
3. Count the remaining warnings,
4. Fail the check if (3) is non-zero.
