tests/kms_properties: Validate properties harder

Make the property validation more thorough:
- validate property flags
- make sure there's an expected number of values/enums
- make sure the possible values make sense
- make sure the current value makes sense
- actually iterate through all planes/crtc/connectors to
  check their properties
- make sure encoders don't expose properties while at it
- check that atomic props aren't exposed to non-atomic clients

Still passes on my ivb. Not tested anything else so far.
