[bedrock] Eliminate BrowserList::get() from //c/b/ part 3

This CL transitions clients of the BrowserList::get() API to more
appropriate APIs available in browser test environments.

This CL specifically focuses on removing remaining usage from
tab_restore_browsertest.cc.

 - RestoreTab() is updated to take a target_browser instead of
   an index into the BrowserList
     - A null target_browser indicates a new browser is expected
       to be created as the result of the restore

 - RestoreGroup() is updated to take a target_browser instead of
   an index into the BrowserList
     - All clients only restore into an existing browser so
       handling for new browsers was removed (simplifying the
       code)

 - The chrome::RestoreTab() browser_command was updated to take a
   BrowserWindowInterface

 - ui_test_utils::BrowserCreatedObserver was used to get references
   to created browsers rather than indexing into an expected position
   in the BrowserList
