[TCP]: Do not present confusing congestion control options by default.
Create TCP_CONG_ADVANCED option, akin to IP_ADVANCED_ROUTER, which
when disabled will bypass all of the congestion control Kconfig
options and leave the user with a safe default.
That safe default is currently BIC-TCP with new Reno as a fallback.
