[igt-dev] [i-g-t V2] lib/igt_kms: New api to iterate over all outputs

[Bhanuprakash Modem]

A few KMS tests are trying to run on all outputs irrespective of
their connection status. So add a new helper to iterate over all
outputs.

V2:
- Fix the commit message
- New helper to iterate over all disconnected outputs
