This change adds 200G settings for Tomahawk 5 to the pg_profile_lookup.

Fixes: aristanetworks/sonic-qual.msft#159

Why I did it
This change is needed in order for some qos tests to run against TH5.

How I did it
Added the values then manually ran qos tests identified in the issue above to verify fix.

How to verify it
Run qos/test_qos_sai.py::TestQosSai::testParameter and confirm that the IndexError in the issue above does not occur.
