Render CDB support field in sfputil CLI output

[bgallagher-nexthop]

What I did

Add a line to the sfputil show eeprom output that indicates whether the transceiver advertises CDB support.

How I did it

sonic-net/sonic-platform-common#721 adds a field to get_transceiver_info that indicates whether the transceiver advertises CDB support.

This PR just renders that field in the CLI output.

How to verify it

Extended existing unit-test.
