Use eslint for sorting our imports (#1637)
* Make eslint sort our imports

* fix missing deps in eslint rule (dae)

Caught on Linux due to the stricter sandboxing

* Remove exports-last eslint rule (for now?)

* Adjust browserslist settings

- We use ResizeObserver which is not supported in browsers like KaiOS,
  Baidu or Android UC

* Raise minimum iOS version 13.4

- It's the first version that supports ResizeObserver

* Apply new eslint rules to sort imports
