Synchronize breakpoints between PowerShell and DAP

[andyleejordan]

We unfortunately clear all existing breakpoints in the PowerShell session on the initialization of the debug server, essentially overwriting them with the breakpoints set in the UI:

PowerShellEditorServices/src/PowerShellEditorServices/Server/PsesDebugServer.cs

Lines 110 to 111 in dd870ec

	// Clear any existing breakpoints before proceeding
	await breakpointService.RemoveAllBreakpointsAsync().ConfigureAwait(false);

and in the attach handler:

PowerShellEditorServices/src/PowerShellEditorServices/Services/DebugAdapter/Handlers/LaunchAndAttachHandler.cs

Lines 413 to 414 in 381e7fe

	// Clear any existing breakpoints before proceeding
	await _breakpointService.RemoveAllBreakpointsAsync().ConfigureAwait(continueOnCapturedContext: false);

Instead, we should find a way to properly synchronize the breakpoints. As they're set in the console, we should update the DAP, and vice versa.
