dot3 Stats collection (sonic-net#3615)

* dot3 Stats collection
What I did

Implement RFC3635 dot3 statistics collection.

Used by sonic-net/sonic-snmpagent#350
Fixes sonic-net/sonic-buildimage#22359

Why I did it

RFC1284 defines dot3 stats that most switch vendors support. This RFC was superseded by RFC3635 which includes 64bit "HC" counters. We need to collect these statistics for use by sonic_snmpagent.
