Daniel Stone d32dfcf833 backend-drm: Enforce content protection for hardware planes 
62626cbfec ensures that the GL render will not render a view's content
to the screen when the surface has requested a higher content-protection
level than the output currently offers.

When the HDCP MR was split into the core content-protection support in !83
and specific DRM support for HDCP in !48 (not yet landed), this opened a
hole where the DRM backend could promote a view to a hardware plane,
even if the output offered a lower protection level than the surface
wanted to enforce.

In the DRM backend, check the desired protection level, and refuse to
promote the view to a hardware plane if the output does not offer
sufficient protection. This will lead to presentation falling back to
the renderer, which may censor the content, reduce quality, etc.
