Add new test for gdb4hpc

[jgphpc]

Cray's gdb4hpc will break if our slurm config varies too much ===> it would be nice to have a reframe check for daint-gpu/daint-mc * gnu/intel/pgi/cce.

While gdb4hpc is normally used inside a salloc session, it will be hard to do that with reframe (?).
It's also possible to launch it in batch mode (-b) but must wait for Cray Case #224617 to be fixed.
I use this issue as a placeholder.

⚠️ there may be a conflict with xalt (i unload the modulefile).

• srun is replaced with:

/opt/cray/pe/gdb4hpc/3.0.10/libexec/guard_proxy -h daint104 -p 36081

daint-gpu
