Support Set-PSBreakpoint showing breakpoints in the editor

By creating a Proxy function of Set-PSBreakpoint, we can fire the breakpoint event as seen in the DAP spec to notify the client that a breakpoint has been added.

This is the really the final feature needed to provide the "console debugging in PSES experience" that feels totally integrated.

Creating a Proxy cmdlet is easy with:

$Metadata = [System.Management.Automation.CommandMetaData]::new((Get-Command Set-PSBreakpoint))
[System.Management.Automation.ProxyCommand]::Create($Metadata)

Then we'll need a way to give the EditorObject the state of the debugger... but mainly the JsonRpcServer object so that we can use it to send the SendNotification( method to send the breakpoint information to the client.

Then we take that proxy function and add something like:

$psEditor.Components
    .GetService([OmniSharp.Extensions.LanguageServer.Protocol.Server.ILanguageServer])
    .SendNotification("breakpoint", [OmniSharp.Extensions.DebugAdapter.Protocol.Events.BreakpointEvent]::new(<#...#>))

with some error handling and we should be good to go.

Comienza leyendo EditorObject.cs y el enfoque de proxy de Set-PSBreakpoint descrito en la issue. Sigue cómo se accede a JsonRpcServer o ILanguageServer y, después, revisa BreakpointEvent en la especificación de DAP y el tipo de protocolo referenciado. Se considera terminado cuando añadir un breakpoint mediante Set-PSBreakpoint notifica al editor con la información del breakpoint y cuenta con manejo de errores.
