lib/igt_kms: Change output->pending_crtc_idx_mask to output->pending_pipe

igt_output_set_pipe with PIPE_ANY used to mean that we bind the output
to any pipe, but this is now a deprecated alias for PIPE_NONE, and
means the output will be unbound.

Because of this it's better to change output->pending_crtc_idx_mask to
an enum pipe, because only a single choice may be given for a pipe.
