Merge #19704: Net processing: move ProcessMessage() to PeerLogicValidation

Browse Source 
daed542a12e0a6a4692aca12a61b84cd55accc33 [net_processing] Move ProcessMessage to PeerLogicValidation (John Newbery)
c556770b5ef4306f10e980daff772bee87daaa30 [net_processing] Change PeerLogicValidation to hold a connman reference (John Newbery)

Pull request description:

  Rather than ProcessMessage() being a static function in net_processing.cpp, make it a private member function of PeerLogicValidation. This is the start of moving static functions and global variables into PeerLogicValidation to make it better encapsulated.
