Add SAI_ATTR_PORT_FW_REVISION to saiport (#2197)

This proposal outlines the addition of a new port attribute designed to provide a standardized method for querying the active firmware revision of a port.

Proposal -

Add label SAI_ATTR_PORT_FW_REVISION under sai_port_attr_h in saiport.h to store firmware related information. This attribute will store a string denoting the current firmware version running on the port. This can denote either the SerDes firmware version or any other vendor specific firmware version that needs to be exported.
