Switch analysis to flutter/packages (#120908)
In preparation for the merge of flutter/plugins into flutter/packaegs,
update the cross-repo analysis to flutter/packages rather than
flutter/plugins.

The flutter_plugins.version file is left intentionally for now to avoid
issues with the roller; it will be removed when the roller has been
updated to roll the other repository.

Flutter SDK dependency versions

The files in this directory specifies pinned versions of various dependencies of the flutter SDK.

The bin/internal/engine.version file controls which version of the Flutter engine to use. The file contains the commit hash of a commit in the https://github.com/flutter/engine repository. That hash must have successfully been compiled on https://build.chromium.org/p/client.flutter/ and had its artifacts (the binaries that run on Android and iOS, the compiler, etc) successfully uploaded to Google Cloud Storage.

The /bin/internal/engine.merge_method file controls how we merge a pull request created by the engine auto-roller. If it's squash, there's only one commit for a pull request no matter how many engine commits there are inside that pull request. If it's rebase, the number of commits in the framework is equal to the number of engine commits in the pull request. The latter method makes it easier to detect regressions but costs more test resources.

The bin/internal/flutter_packages.version file specifies the version of the flutter/packages repository to be used for testing. The flutter/packages repository isn't an upstream dependency of flutter/flutter; it is only used as part of the test suite for verification, and the pinned version here makes sure that tests are deterministic at each flutter/flutter commit.
