fix build of 64bit PETSc and Trilinos in the same deal.II DAG (#3223)

Browse Source 
Declare that (i) Trilinos can be only built against 32bit Hypre
(ii) SLEPc can not be built with Arpack when 64bit indices are used
(iii) reflect those constraints in deal.II's depends_on
While there, add extra release flags for best performance.
