Adds support for setting breakpoints in untitled/unsaved files for Windows PowerShell 5.1. This aligns the breakpoint validation behaviour with the PowerShell 7.x API so that a breakpoint can be set for any ScriptBlock with a filename if it aligns with the client's filename.
Updates the sequence of launching and attaching scripts until after configuration done is received. This aligns the behviour of starting a debug session with other debug adapters. A side effect of this change is that it is now possible to set breakpoints and do other actions in an attached runspace target during the initialisation. Also adds a new option `NotifyOnAttach` for an attach request which will create the `PSES.Attached` event before calling `Debug-Runspace` allowing attached scripts to wait for an attach event.
