Add factory functions for Main/Test/Sig/Reg chainparams

Browse Source 
This normalizes the behavior of initializing Main/Test/Sig/Reg
chainparams with RegTest/SigNet chainparams. These factory functions can
also easily be used from a context without an instantiated ArgsManager,
e.g. from libbitcoin kernel code, unlike the existing CreateChainParams
method.
