Don't call unnecessary pause/resume for LaunchIntoPinnedStackPipActivity

In ARC, we added a workaround where a batched pause/resume is
called onOcclusionChanged to handle a bunch of edge cases for
activities that support PIP (ag/7677752).

However, LaunchIntoPinnedStackPipActivity assumes to be called only
once in each CTS, the workaround must not be applied to the
activity. We can do this just by unsupport PIP for this activity.

I believe this activity is not expected to be PIP, so it's safe to
unsupport it.
