Add support for Coveralls to CI

This commit provides support for Coveralls CI by leveraging the existing Gcov build configuration, adding configuration so that gcovr generates coverage data in Coveralls JSON format, and adding steps to the CI build job that are activated only if the matrix entry is configured for coverage, which generate coverage data and deliver it to Coveralls.
