tests/kms_frontbuffer_tracking: Add tiling to test_mode

This will allow us to do tests with different tile types, for now
all tests will continue to run with the default X tiling.
It will be used in upcoming patches.

It also allow user to run all tests with liner tiling when set by
parameter.

v2:
- renamed tile to tiling (Ville)
- added to the commit message that this will be used in upcoming
patches
