[igt-dev] [PATCH v14 5/5] tests: gem_exec_basic: add "exec-ctx" buffer execution demo test

The "exec-ctx" is a 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 "exec-ctx" subtest simply gets the list of engines, binds
them to a context and executes a buffer. This is done through a
new "for_each_engine2" loop which iterates through the
engines.
