Add config, show, and clear CLI commands for PRBS (Pseudo-Random Bit Sequence) link diagnostics. Includes enabling and disabling prbs config, 'show interfaces prbs <>' for per-lane BER and lock status results with JSON support, 'clear prbs results' for STATE_DB cleanup, shared utility functions in prbs_util.py, and full Command-Reference documentation with usage examples.

Relocate PRBS enable/disable commands from 'config interface prbs' to 'diag interface prbs' to reflect their transient, diagnostic nature. - Move config/interface_prbs.py to diag/main.py as standalone CLI group - Write PRBS config to DIAG_PORT_TABLE in APPL_DB via ProducerStateTable instead of CONFIG_DB PORT table (transient, no config save/reboot) - Update Command-Reference.md with new diag CLI examples Signed-off-by: Pavan Naregundi <pnaregundi@marvell.com> Signed-off-by: Parthiv Shah <parthiv@marvell.com>

What I did
Added PRBS (Pseudo-Random Bit Sequence) CLI support
How I did it
Created diag/ as a new top-level CLI group (diag/init.py, diag/main.py) registered in setup.py
Added show interfaces prbs status in show/interfaces/prbs.py with optional -i and --json flags; reads from STATE_DB
Added sonic-clear prbs results in clear/main.py; guards against clearing while a test is still running
How to verify it
Previous command output (if the output of a command-line utility has changed)
New command output (if the output of a command-line utility has changed)
