disp: msm: dp: optimize sim function handling in dp_debug

Remove edid/dpcd simulation function from dp_debug and calls to
sim bridge instead to simplify dp_debug module. Also add mst edid
support and mst hpd simulation from aux level.

Move selected mode from dp_debug module to dp_panel module to
simplify mst handling and decouple dp_debug from main dp driver.

Remove custom edid/dpcd mode from dp_panel and dp_aux module.
Remove mst connector list handling from dp_display module.
