[igt-dev] [i-g-t V2 1/5] lib/drmtest: Add helpers to check and require the XE driver

[Bhanuprakash Modem <bhanuprakash.modem@intel.com>]

In order to add support for features specific to the XE driver, add
helpers for checking and requiring the driver.

This patch will also update igt_require_intel() to support XE, and
create new helper igt_require_i915() as both i915 & XE belongs to
intel.

V2: - Re-use existing helpers for igt_require_intel (Mauro)
