Editor remote debugger should allow to listen on all interfaces

Tested on Windows, doubt its relevant though

Issue description

As of right now (before https://github.com/godotengine/godot/pull/98282/), the docs for the editor setting network/debug/remote_host state: This can be set to 0.0.0.0 to allow external clients to connect to the remote debugger (instead of restricting the remote debugger to connections from localhost).

However, in the editor this is exposed as a dropdown selection of available local network interface adressses. "All" is not an option, but I'd indeed expect it to work, as the case described above makes sense (and is probably what I'd use more often rather than restricting this to, say, a specific IPv4 interface).

As this setting is a string, it may work when set from code, in which case this is more of a Editor UI issue, where we need to inject an additional wildcard/any setting for the dropdown.

Steps to reproduce

• Open editor, browse editor (not project) settings, search for "remote host", notice the dropdown doesn't allow selectin all interfaces

~The "remote host" option is not for "listening" but for "connecting", i.e. it's the IP address the client will connect to (the editor address), and must thus be a valid IP (i.e. it can't be 0.0.0.0, since you can't connect to 0.0.0.0)~

EDIT: Ah, nevermind, I see this is just the editor part, so indeed, that should allow wildcards.

So the problem here, is that that settings is used to configure the running client (in editor/export/editor_export_platform.cpp).

Which means we would need to split this in 2 parts (one for the runtime configuration, one for the server bind address), which is IMO even more confusing.
