[Chassis] parse 400g zr port config from minigraph (#11616)

Signed-off-by: Arvindsrinivasan Lakshmi Narasimhan arlakshm@microsoft.com

Why I did it
Generate the port configuration required 400G ZR port from minigraph.

How I did it
Add parse logic to get tx_power and laser_freq from LinkMetadata section of the minigraph.
Add UT for packet-chassis and voq chassis

How to verify it
UT
