drm/tests: hdmi: Add macro to simplify EDID setup

Browse Source 
Factor out the HDMI connector initialization from
drm_kunit_helper_connector_hdmi_init_funcs() into a common
__connector_hdmi_init() function, while extending its functionality to
allow setting custom (i.e. non-default) EDID data.

Introduce a macro as a wrapper over the new helper to allow dropping the
open coded EDID setup from all test cases.

The actual conversion will be handled separately; for now just apply it
to drm_kunit_helper_connector_hdmi_init() helper.
