Make the examples/catalog instructions a bit less confusing:
* Make the README.md file provide explicit instructions about how to
  run each example.
* Try to clarify that the lib/main.dart message is instructional and
  not an error message.

Additionally, adjust examples/layers/lib/main.dart to be consistent
with examples/catalog/lib/main.dart.

Fixes #22640.

Testing Done:
* Ran `flutter run` from examples/catalog and from examples/layers,
  saw the updated message.

Fixes https://github.com/flutter/flutter/issues/24257

* Update IntelliJ project template files

* Add ignored file

* Fix test

* Restore comma

Landing on red in order to fix the build.

* Fix multi-step build handling process.

Stop listening for new step updates after 'all done.' log message. Make sure that we don't delete file too soon, until listener had a chance to process the 'all done' message.

Fixes https://github.com/flutter/flutter/issues/18750

* Emit 'all output' explicitly when build process is done.

Unfortunately, device lab does not have the capacity for merge method
rebase. It's essentially DoSing device lab: The last engine rebase has
been processing for 6h now and it is still not done :(

This reverts commit f3a4f7e8.

Accidental merge on red.

This generates a zip file containing all of the docs, and uploads it when we publish docs, as well as a
Dash/Zeal docset that contains a feed of the docs.

Addresses at least part of #9955
