[igt-dev] [PATCH V4] [PATCH i-g-t][V4] tests/i915/gem_ringfill:Added __for_each_physical_engine to utilize all available engines.

[satyavat <satyavathi.k@intel.com>]

Replaced the legacy for_each_engine* defines with the ones implemented
in the gem_engine_topology library.

subtest that is modified: Ringfill

V2
Added "Test" name in dynamic subtest to avoid
"-" during subtest list.

corrected DRM open call .

V3
Removed "-" from mode array
removed Test name in dynamic subtest

V4
corrected fd handle in igt_fork
