[ansible][minigraph] add support for adding autonegotiation in minigraph templates and fanout EOS (sonic-net#13990)

These changes add a support for adding auto negotiation to specific testbed based on variables defined in ansible

Two things are required for autoneg support

1. autoneg_enabled : True
must be enabled in inventory files
2. t0 topo file must have a port list for autoneg
Example:
intfs : [1, 2, 3, 4, 5, 6, 7, 8]
With these changes the PR includes changes to pick the port numbering from topo file and apply minigraph parsing changes such that during deploy-mg or gen-mg the required ports have autoneg and deployment is clean with link up
