Same as ADEV, currently the CLI prompts for another port if 4200 is busy but the toolchain doesn't support prompts.
By defaulting to 4201 we avoid regular CLI apps from preventing to run the dev-app
(cherry picked from commit 9bb4f02bef)
This moved the `NG_FORCE_TTY` from individual `ng_web_app` rules to a global Bazel build flag as this is also needed for integration tests that under the hood run `ng serve` .
Force adev and devapp to run in non-TTY mode so it doesn't create a prompt that can't be interacted with. This will initially have no effect,
but the fix is expected to land in CLI to make this work as expected in the next few days.
