This auto-formats all *.dart files in the repository outside of the
`engine` subdirectory and enforces that these files stay formatted with
a presubmit check.
**Reviewers:** Please carefully review all the commits except for the
one titled "formatted". The "formatted" commit was auto-generated by
running `dev/tools/format.sh -a -f`. The other commits were hand-crafted
to prepare the repo for the formatting change. I recommend reviewing the
commits one-by-one via the "Commits" tab and avoiding Github's "Files
changed" tab as it will likely slow down your browser because of the
size of this PR.

Closes#97595
The prior approach of manually diffing the entire log chain is less
efficient, and only found the original branch point ignoring subsequent
merges. The limitation forced PR workflows into rebasing and force
pushing new history to get the branch point far enough for CI to pass.
Use `git merge-base` to find the latest common commit with the main
branch.
Add an `allowFailure` argument to the `git` utility to use a more
specific failure in the case of no shared history when this command will
fail with a generic error.
Use `^branch` with the `git log` commands to exclude shared history and
more easily count the unique commits on each branch.
Drop the `Commit` abstraction. Parse directly to timestamp or line counts.
