[igt-dev] [PATCH v16 5/8] tests: gem_exec_basic: add engine discovery test

[Andi Shyti <andi.shyti@intel.com>]

The "exec-engines-ctx" and "exec-physical-engines-ctx" are two
demo subtest inserted in the gem_exec_basic
test. The main goal is to reach the engines by using
the new uapi interfacing with 'gem_topology_has_engine()'.

The two cases get the list of both virtual and physical and only
physical engines and makes sure they actually exist.
