[PATCH i-g-t v4 1/3] tests/i915/i915_suspend: Add s2idle and s3 subtests without i915

[Riana Tauro]

From: "Tauro, Riana" <riana.tauro at intel.com>

Add new tests basic-s2idle-without-i915 and basic-s3-without-i915
to exercise s2idle and s3 cycles to know the system wide
health of suspend/resume

v2: rebase
v3: rebase
v4: optimized test by skipping s3 if mem_sleep is s2idle (Anshuman)
