Reference-LAPACK PR 445, fixing their issue 263

from Reference-LAPACK PR 438

as explained by serguei-patchkovskii in Reference-LAPACK/lapack#438 (comment) , passing in an index of 1 instead of N leads to a standards violation accessing matrix A in SLASET, i.e. undefined behavior

Based on how the surrounding functions in lapack.h are handling the
parameters, particularly the ?ggsv?3-variants of the affected functions

Fix various wrong calls to SLASET/DLASET in the EIG part of the LAPACK testsuite

* Fix misnaming of LAPACK_?ggsvp and ?ggsvd function prototypes as LAPACKE_

* Drop the LAPACKE matrix_layout parameter from the argument lists, change ints to pointers and add missing work arguments.
