[PATCH i-g-t v3] tests/kms_tiled_display: Skip if connectors are not of same type

[Pranay Samala]

Tiled display setups require all involved DP connectors to be of the
same type. This patch adds a check to skip the test when
connector types differ, preventing invalid configurations and reducing
confusing test failures.

v2: Replace igt_assert with igt_skip_on_f to skip the test.
v3: Add supported port sync in commit message (Ankit)
    Ensure if connector type is not DRM_MODE_CONNECTOR_Unknown (Ankit)
