Combine Sign-In/Sign-Up and Teacher Account Required gates into distinct pages

[TurnerRiley]

There are two places we currently use the simple signed-out or student gating components: joining sections and workshop enrollments. They had virtually identical components and we needed a way to be able to show these views easily upon clicking a button, so it made sense to just combine these into two pages so they can more easily be re-used elsewhere.

As part of this, I also removed the "Cancel" button that was on the teacher upgrade view because it had originally just been copied over from the LTI Link Account component and just functioned to cancel the creation of a user mid-sign-up. I'm happy to bring it back if desired, but I imagine if we want a button to take the user back to where they were we'd probably want that to be the link of the "Keep student account" card's button (instead of it sending the user to studio.code.org/home).

The sign-up/sign-in gate will live at /logged_out and the gate telling students they must be teachers to view will live at /teacher_account_required. This should make it easier to show the gates by just sending the user to one of the following links:

• /logged_out?source_page=[name of source page for logging]&return_to=[url to bring user back to]
• /teacher_account_required?source_page=[name of source page for logging]&return_to=[url to bring user back to]

Note: Uses of these URL's will require the parameters to be encoded since all of the logging source_page values used already have a space in them (e.g. "join section" and "workshop enroll") and the return_to URL's will have forward slashes.

lgtm! I love the cleanup and consolidation of components that can be reused
