[VSCode] Run windows based duo chat e2e tests in CI

Problem

VScode may perform differently on Windows.

Solution

We need to run e2e tests on Windows agents to catch such problems early. We can use LSP windows jobs as a reference here.

1. We want to have a windows agent that would run a (sub)set of integration tests of vscode
2. In case not all tests passes on windows on any reason, we need to ensure the smoke-tests subset is at least running and passing. This includes basic tests, like:
   1. authenticate,
   2. duo-chat integration
   3. code suggestions
