Release a headless executable for macOS #18970

Is your feature request related to a problem? Please describe.

I posted earlier that I'm working on an Electron-based UI for bitcoind. I would like to embed an executable version of bitcoind within my app but I couldn't figure out how to do that for macOS.

(I haven't tried to do it for Linux or Windows, but I assume it's easier to do because bitcoind is part of the release on those platforms. I just need to copy it to my app's directory and execute it from there and it should work.)

Describe the solution you'd like

Release an executable version of bitcoind for macOS.

Describe alternatives you've considered

I tried to build bitcoind on my macOS machine then execute it on another macOS machine, but it complained about missing dependencies (boost I think). I don't know make or autoconf so that was a dead-end for me.

Now I'm asking potential users of my app to have Bitcoin Core UI running with server=1 in bitcoin.conf. Otherwise my app won't work. It would be so much better if I could make this a seamless process by embedding bitcoind within my app.

So it turns out that there's a bitcoind binary included in the tar.gz archive on the download page. Thanks to @achow101's help on StackExchange for that.
