lib/igt_kms: Add helpers to count and iterate planes from output

With helpers to count and iterate among planes of a given type from the
pipe in place, we can use them with the current pipe for the output to
make it possible for tests to use them (the pipe struct is not currently
easily exposed to tests and exposing it adds unnecessary complexity).
