Fortran: PACK intrinsic should not try to read from zero-sized array

libgfortran/ChangeLog:

PR libfortran/103634
* intrinsics/pack_generic.c (pack_internal): Handle case when the
array argument of PACK has one or more extents of size zero to
avoid invalid reads.

gcc/testsuite/ChangeLog:

PR libfortran/103634
* gfortran.dg/intrinsic_pack_6.f90: New test.

(cherry picked from commit 1c613165a55b212c59a83796b20a1d555e096504)
