In addition to the changes in this commit, gjs now
restricts the use of the Format module and initFormat.
We can't really replace those for translatable strings
until xgettext gains support for template strings, so
leave that bit out for now.
The other notable change is that gjs now requires
jsdoc comments. We can't plainly enable those options
without a massive amount of work first, but let's see
how requiring doc comments for new code goes.

As of mozjs68 (gjs-1.64) `globalThis` is recommended over `window` and
it makes more sense in this context anyways. Migrate the few instances
of `window` we use and adjust the eslint configuration.
`window` will continue to resolve to `globalThis`, so this won't affect
extensions or other downstream users.
