cmInstallGenerator: Refactor computation of absolute install dest

Replace the GetInstallDestination method, which looked up the
Destination ivar, with a new ConvertToAbsoluteDestination method that
takes the nominal destination as an argument.  Update call sites
accordingly.  This will allow some clients to transform the install
destination before calling the method.
