Moves the tab restore structs Entry, Tab, Group, and Window out
of the TabRestoreService and into its own file.
The goal of this CL is to decouple LiveTabContext from
TabRestoreService, which includes LiveTabContext. Doing this will allow
us to pass the Tab, Group, and Window types as parameters to functions
such as LiveTabContext::AddRestoredTab instead of passing all the fields
of the objects individually.
