"Create New Library" Form

[bradenmacdonald]

When clicking the "New Library" button in the course authoring MFE:

Case 1: If the LIBRARY_MODE is v1 only, it redirects to the legacy Studio libraries page:

Case 2: If the LIBRARY_MODE is mixed and the user is currently on the "Legacy Libraries" tab, it also redirects to the legacy Studio libraries page.

Case 3: Otherwise, implement a new "Create library" page that matches the version in the library authoring MFE. Filling out the form should successfully create a new v2 library. Errors should be displayed.

@jmakowski1123 @marcotuts The sandbox has been updated and the "Cancel" button has been added to the "Create new library" form (see slack thread), it's ready for your review when you get a chance.
