tests: Introduce i915 directory

We can already move all the tests with distinct prefixes: gem_, gen3_
and i915_.

pm_ and drv_ tests will follow in batches, so we can do the
adjustments in the reporting/filtering layer of the CI system.

v2: Fix test-list.txt generation with meson
v3: Fix docs build (Petri)
