Merge #14007: tests: Run functional test on Windows and enable it on Appveyor

661ac15a4a appveyor: Run functional tests on appveyor (Chun Kuan Lee)
2148c36b6e tests: Make it possible to run functional tests on Windows (Chun Kuan Lee)

Pull request description:

  This PR do the following things:
  - Make functional tests compatible with Windows
  - Print color output in functional tests for Windows 10
  - Run util and functional tests on appveyor
  - Do not run symlink tests on Windows

  Note:
  - The wallet_multiwallet.py fail is unrelated to the test framework, it's a bug related to c++ code or maybe dependencies. `bitcoind` would exit with 0xC0000005(Access violation) during shutdown occasionally. Disable this for now.
  - Not using `--failfast` because this is still in experimental. We should track if there is any other error.
  - Disable ZMQ tests because the python zmq library could cause access violation sometimes.
  - Disable `feature_notifications` because Bitcoin Core handles the command in different thread, whicha can cause a race condition.
