This will help transition to ES Modules as we won't be able to expose a magic "chrome" ESM.
Also, most of these symbols are exposed as global already.
All but:
* `components` which is `Components`,
* `CC` which is `Components.Constructor`,
* `Cm` which is `Components.manager`.
$ sed -ie "/require(.chrome.)/d" $(git grep -l 'require("chrome")' devtools/)
+ manual edits for all three exceptions
