[PATCH i-g-t v2] tests/intel/xe_oa: Check gtidle before rc6 disable test

[Soham Purkait <soham.purkait@intel.com>]

Rc6 disable test has been modified in order to check the
presence of gtidle node in sysfs gt0 path through the following
code snippets :
igt_require(xe_sysfs_gt_has_node(drm_fd, 0, "gtidle")).

As of now only Render GT (gt0) is used for rc6 disable test through OA
activation. Standalone Media (gt1) is not supported yet for the same.
