Subject: multiprocess: Add new bitcoin-gui, bitcoin-qt, bitcoin-wallet init
 implementations

Add separate init implementations instead of sharing existing bitcoind
and bitcoin-node ones, so they can start to be differentiated in
upcoming commits with node and wallet code no longer linked into the
bitcoin-gui binary and wallet code no longer linked into the
bitcoin-node binary.
