[perf] Use only one StringBuilder for generate unique facelets identifiers
--------------------------------------------------------------------------

                 Key: MYFACES-3427
                 URL: https://issues.apache.org/jira/browse/MYFACES-3427
             Project: MyFaces Core
          Issue Type: Improvement
            Reporter: Leonardo Uribe
            Assignee: Leonardo Uribe


The code that generate unique identifiers, like UIComponentBase.getClientId() and others inside
facelets are operations that are called very frequent, so it is necessary to ensure that code
is as fast as possible and use few memory resources

Also, doing some performance tests I notice Long.toString(long, radix) is too expensive. It
creates a lot of unnecessary String objects.

In practice, we should prevent create object instances in such locations, and use only one
StringBuffer if possible.
