(core) Site Switcher and Other Sites

Summary:
A new section, Other Sites, will now be shown on the All Documents page when:

 - A user is on a personal site and has access to other team sites.
 - A user is on a public site with view access only.

In addition, a site switcher is now available by clicking
the site name in the top-left section of the UI next to the
Grist logo. It works much like the switcher in the Account
menu.

Test Plan: Browser tests.
