edge: Remove GPRS RBB based window handling methods 

These methods have been replaced and are no longer used since the
commit "edge: Use bitvec based window methods for EGPRS", with the
only exception of TbfTest.cpp.

Remove the methods and update TbfTest.cpp by using the bitvec based
methods instead.
