Added UI for clearing Chrome Sync data

- Created 2 tabs, one for for clearing local browsing data, one for clearing server data
- Refactored the old local browsing code to use a grid layout rather than less-wieldy math
- Controls on all tabs block while, closing dialog is disabled, new throbber is going while clear is in progress
- Clear server tab will be behind a flag until I deploy the server endpoint
- Retained old clearing behavior: dialog closes on successful lear
- Clear server UI only visible if user is syncing

Outstanding issues:
- Clearing currently causes an account to become unusable.  The cause of the issue is a known problem with auth; currently investigating a fix
- Unlike local clearing, clearing server data is more likely to error out.  For now I just show a label next to the clear button that says Error, allowing the user to try again

BUG=54349
TEST=Clear from UI, or run sync backend tests checked in for issue 54280
