J. Ryan Stinnett 30b2b7ce44 Bug 1271084 - Apply ESLint autofixes to ignored /devtools files. r=tromey
For simple rules like function spacing, we can auto-fix these across the code
base so they are followed in a consistent way.

To generate this patch, I ran:

./mach eslint devtools --no-ignore --fix

After this, I reverted any changes to third party files that we really do want
to ignore.
