Transition from TravisCI to GitHub CI (#7444)

Convert the continuous integration process to use GitHub's internal
CI cloud.  Allows us to run up to 20 jobs in parallel, speeding up
CI immensely.  Keep a short Travis-CI run, too, just for sanity and backup.

Uses new keys and secret when publishing a release to
esp8266.github.io.
