lib/igt_debugfs: Add functions/tests for controlling/testing HPD storm logic
Recently we added i915_hpd_storm_ctl into i915's debugfs directory,
which allows us to control the thresholds i915 uses for detecting
hotplug interrupt storms from userspace, along with the ability to
entirely disable them. This adds some helper functions into IGT to
enable making use of this feature, along with adding some chamelium
tests for it.
