In cases, where the caller is looking for the locale to be used for JS Intl API,
we can now replace it with `undefined` which causes JS Intl API to use the default
locale which since bug 1346674 is resolved to the app locale.
This allows us to remove a lot of calls for the app locale.
The remaining ones are split between `AsBCP47` and `AsLangTag`.
Here, the `AsLangTag` is used, as described in the API docs, for cases where
the language string is used for localization purposes, such as language negotaition
matching to our language resources etc.
`AsBCP47` is used when the returned value is handed over to ICU API.

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.
