Fast open script in Rider from Godot

[van800]

Establish connection between Rider and GodotEditor.
When Godot calls OpenScript - call Rider to open script using that connection.

It works now (Rider EAP 241.9959.26) if you set up Rider as external code text editor (for .gd scripts) . Double click opens the script in Rider and treats the directory that contains this script as root directory in Rider. This should probably somehow change into treating the project root as a root directory for Rider though.

@Sygan This issue is about making a different implementation.
When both Rider and GodotEditor are already running we can use the Ide.Messaging introduced in here #102 to pass path, line, column to Rider and open it.
Instead of (I think) what happens now new process starts, uses some other mechanics to detect that Rider with this solution is already opened and then passes it the control and exits.

However this issue is very low priority, since current implementation works good without complaints. I would rather leave it as it is.
