[TCPStore] Remove deprecated constructor (#136004)

While looking at TCPStore code again and found it confusing that we still keep the deprecated constructor for TCPStore in cpp while we don't expose it in python via pybind already. I checked both internal and external, all use cases in cpp (aside from unit test fixed in this PR) already moved to using option. So let's remove this legacy constructor to avoid confusion.
