[Arista 7050cx3] add dummy MMU configurations for Arista-7050CX3-32S-C32 (#5798)

Browse Source 
- Why I did it
On Arista-7050CX3-32S-C32, there are constant stream of errors like following.

Nov 3 21:56:24.415190 str2-7050cx3-acs-06 NOTICE swss#orchagent: :- registerInWdDb: No lossless TC found on port Ethernet68

Which causes:

loganalyzer to claim test failed.
leaving the system without MMU configuration. Which couldn't be good for any IO test.
- How I did it
Added these MMU configuraions are copied from another platform and guaranteed to be incorrect for hwsku Arista-7050CX3-32S-C32.

Adding them so that we have A MMU configuration and the system won't throw a whole bunch of errors and leave MMU unconfigured. The correct MMU configuration will come later.

This configuration is definitely not suitable for testing system performance or QoS behavior.

- How to verify it
Test will have chance to pass. Ran a few test that would fail otherwise.
