Load windows-process-tree from appRoot at runtime

Add _loadWindowsProcessTree helper to resolve @vscode/windows-process-tree via env.appRoot and eval('require') so the native .node addon is loaded at runtime (bypassing webpack's require interception). Update AttachProcessProvider to use this loader instead of a direct require. Update unit tests to remove the direct import of the windows-process-tree module and stub the new _loadWindowsProcessTree method. Clarify webpack comment to document the runtime loading approach. Also add path and env imports used by the new loader.
