Describe the bug

A warning:

A debug session is currently active. Changes to your Go files may result in unexpected behavior.

appears in reference to a debug session which is inconsequential to the Go environment.

Steps to reproduce the behavior:

1. Open workspace which combines a Go project (workspace has a folder which contains go.mod) and a Node.js project
2. Start debug session for the Node.js project
3. Edit Go source code
4. Trigger auto-save or save the changes to the Go file

I also observed this issue while working on a go file in vscode-go project.
The relevant code:

vscode-go/src/goMain.ts

Line 596 in 855baeb

if (vscode.debug.activeDebugSession) {

We need to inspect the DebugSession and check the active debug session is relevant.

Change https://golang.org/cl/269137 mentions this issue: src/goMain: do not show warning if the active debug session is not ours
