Upgraded jQuery to version 2
## What does this MR do?
Upgrades jQuery to 2.2.1.
Had to include the task_list JS file directly as it includes jQuery 1 directly https://github.com/github-archive/task_list/blob/master/app/assets/javascripts/task_list.coffee#L8 so when we change jQuery to `jquery2` it was including both jQuery 1 & 2.
## Are there points in the code the reviewer needs to double check?
For any JS errors

Closes#12440

- Move the `TwoFactorAuthsController`'s `new` action to `show`, since
the page is not used to create a single "two factor auth" anymore. We
can have a single 2FA authenticator app, along with any number of U2F
devices, in any combination, so the page will be accessed after the
first "two factor auth" is created.
- Add the `u2f` javascript library, which provides an API to the
browser's U2F implementation.
- Add tests for the JS components

First, the autosize library was being too controlling and removed the
`resize` property from any elements to which it was attached, removing
the drag handle.
Second, we detect when the user manually resizes an autosize textarea,
and then remove the autosize behavior from it and increase its
max-height.
This should allow for the best of both worlds.
Closes#12832
- No longer depends on the "hidden checkbox".
- No longer depends on manually storing/restoring the scroll position.
Instead, we take advantage of jquery.scrollTo.
- Event-based.
- Simplifies the state-based styling.
