Configurations for the flutter engine repository.

The schedulers pull commits indirectly from GoB repo
(https://chromium.googlesource.com/external/github.com/flutter/engine)
which is mirrored from https://github.com/flutter/engine.

Try jobs use github directly but are also registered with luci-cq
to take advantage of led recipe builder tests.
