This reverts commit 5fd259be.

This modifies the flutter update-packages and flutter update-packages --force-upgrade commands so that the many invocations of "dart pub get" in each repo project run in parallel instead of in series.

* Updated skipped tests for flutter_tools.

* Turned the flaky overall_experience test off as it was still failing on CI.

This changes the "Waiting for another flutter command to release the startup lock..." message output so that it appears on stderr instead of stdout. When it appears on stdout, it can mess up collection of the output. For instance, if you run flutter --version --machine and you're expecting JSON output, then you'll get non-JSON output even though the lock is released and you eventually would get what you're asking for.

Disable the automatic "pub get" if the project is using a third-party tool for linking dependencies. (#86177)

This reverts commit 8b6baae4.

Our current top crasher is an unclear error when ProcessManager fails to resolve an executable path. To fix this, we'd like to being adjusting the process resolution logic and adding more instrumentation to track failures. In order to begin the process, the ProcessManager has been folded back into the flutter tool
