MAINTAINERS: Add Tvrtko as drm/i915 co-maintainer

Add Tvrtko Ursulin as a co-maintainer for drm/i915 driver.
Tvrtko will bring added bandwidth and focus to the GT/GEM domain
(drm-intel-gt-next).

This will help with the increased driver maintenance efforts, allows
alternating the drm-intel-gt-next pull requests and also should increase
the coverage for the maintenance in general.
