[PATCH i-g-t] tests/kms_display_modes: Skip test if big joiner display is connected

[Jeevan B <jeevan.b@intel.com>]

High-resolution displays that support big joiner can cause extended mode
tests to fail. This commit introduces a check to skip these tests if a
big joiner display is connected, ensuring the test suite runs smoothly
without unnecessary failures.

v2: Add ultra joiner check.
