kms_content_protection: Add Content Protection test

Pretty simple test:
- picks the hdcp capable output with suitable pipe and apply modeset.
- checks the connected sink's hdcp capability through debugfs
- apply a FB and wait for the flip completion.
- clears the content protection property
- verifies that it clears
- sets the content protection property to desired
- verifies that it transitions to enabled
- incase of timeout three reattempts are implemented
- clear the content protection property and modeset on the crtc

Above steps are repeated on all HDCP capable connectors for both
legacy and atomic subtests.

v2:
  dynamic subtests are dropped [Daniel]
v3:
  debugfs is used to detect the sink's hdcp capability [Daniel]
  data structure is made as global variable.
v4:
  debugfs file from connector's debugfs dir is used [Daniel]
v5:
  i915_debugfs_connector_dir() usage is modified [Chris]
