Merge #21162: Net Processing: Move RelayTransaction() into PeerManager

680eb56d82 [net processing] Don't pass CConnman to RelayTransactions (John Newbery)
a38a4e8f03 [net processing] Move RelayTransaction into PeerManager (John Newbery)

Pull request description:

  This is the first part of #21160. It moves the RelayTransaction() function to be a member function of the PeerManager class. This is required in order to move the transaction inventory data into the Peer object, since Peer objects are only accessible from within PeerManager.
