drm/amd/display: Add tags for indicating mst progress status

Browse Source 
[Why & How]
In order to leverage igt tool to maintain mst feature, expose new
debugfs entry "mst_progress_status".

In our dm flow, record down the result of each phase of mst and user
can examine the mst result by checking whether each phase get completed
successfully.
