Merge bitcoin/bitcoin#30509: multiprocess: Add -ipcbind option to bitcoin-node

Pull request description:

  Add `-ipcbind` option to `bitcoin-node` to make it listen on a unix socket and accept connections from other processes. The default socket path is `<datadir>/node.sock`, but this can be customized.

  This option lets potential wallet, gui, index, and mining processes connect to the node and control it. See examples in #19460, #19461, and #30437.

  Motivation for this PR, in combination with #30510, is be able to release a bitcoin core node binary that can generate block templates for a separate Stratum v2 mining service, like the one being implemented in https://github.com/Sjors/bitcoin/pull/48, that connects over IPC.

  Other things to know about this PR:

  - While the `-ipcbind` option lets other processes to connect to the `bitcoin-node` process, the only thing they can actually do after connecting is call methods on the [`Init`](https://github.com/bitcoin/bitcoin/blob/master/src/ipc/capnp/init.capnp#L17-L20) interface which is currently very limited and doesn't do much. But PRs [#30510](https://github.com/bitcoin/bitcoin/pull/30510), [#29409](https://github.com/bitcoin/bitcoin/pull/29409), and [#10102](https://github.com/bitcoin/bitcoin/pull/10102) expand the `Init` interface to expose mining, wallet, and gui functionality respectively.

  - This PR is not needed for [#10102](https://github.com/bitcoin/bitcoin/pull/10102), which runs GUI, node, and wallet code in different processes, because [#10102](https://github.com/bitcoin/bitcoin/pull/10102) does not use unix sockets or allow outside processes to connect to existing processes. [#10102](https://github.com/bitcoin/bitcoin/pull/10102) lets parent and child processes communicate over internal socketpairs, not externally accessible sockets.
