Adds missing localization generation for widget translations
I ran into this issue when I was trying to generate files for
https://github.com/flutter/flutter/pull/169150/files, and found out the
files were being generated for cupertino and material but not widgets.
## Pre-launch Checklist
- [x] I read the [Contributor Guide] and followed the process outlined
there for submitting PRs.
- [x] I read the [Tree Hygiene] wiki page, which explains my
responsibilities.
- [x] I read and followed the [Flutter Style Guide], including [Features
we expect every widget to implement].
- [x] I signed the [CLA].
- [x] I listed at least one issue that this PR fixes in the description
above.
- [x] I updated/added relevant documentation (doc comments with `///`).
- [x] I added new tests to check the change I am making, or this PR is

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.

When I added localizations for shortcut keys, I added some that actually can't be shortcut keys, so I'm removing them again. These are mostly Japanese-specific keys that don't even appear on modern keyboards for the most part.
Also, added menuBarMenuLabel for an accessibility label for menu bar menus.
I modified the code for the localization generation scripts to add a --remove-undefined flag that will remove any localizations that don't appear in the canonical locale.
