This PR injects a "realm" component to the storage base URL when the contents of the file `bin/internal/engine.realm` is non-empty.
As documented in the PR, when the realm is `flutter_archives_v2`, and `bin/internal/engine.version` contains the commit hash for a commit in a `flutter/engine` PR, then the artifacts pulled by the tool will be the artifacts built by the presubmit checks for the PR.
This works for everything but the following two cases:
1. Fuchsia artifacts are not uploaded to CIPD by the Fuchsia presubmit builds.
2. Web artifacts are not uploaded to gstatic by the web engine presubmit builds.
For (1), the flutter/flutter presubmit `fuchsia_precache` is driven by a shell script outside of the repo. It will fail when the `engine.version` and `engine.realm` don't point to a post-submit engine commit.
For (2), the flutter/flutter web presubmit tests that refer to artifacts in gstatic hang when the artifacts aren't found, so this PR skips them.
Fixes#124252, finishing work on the umbrella tracking issue, #126126.
Essentially, after this PR, no (non-test) code should be be referencing/invoking the java home or binary paths.
* Move linux-x64-flutter-gtk.zip to linux-x64-debug location.
linux-x64-flutter-gtk.zip is being uploaded twice to linux-x64-debug
and linux-x64 as part of making a soft transition to use linux-x64-debug
location. This PR starts using the copy inside linux-x64-debug to later
remove the duplicated upload.
* Also move arm64.
* Do not override output dir.
The dependency is currently uploaded to two different locations. This
change is required to remove the duplicate uploads and their
corresponding tech debt.
