Mark some in-product help actions as not user triggered.

Up until now, all actions related to in-product help have been
considered directly triggered by the user, which is not necessarily
the case, as some of them are more a by-product of other actions.

This leads to in-product help being very prominent in some of
helpful dashboards we have for these types of metrics, and it
is swamping other entries.

For now, the following in-product help actions are kept:
*   InProductHelp.Dismissed:
    *   This is kept because it is in fact a user action to dismiss
        the in-product help.
*   InProductHelp.ShouldTriggerHelpUIResult.Triggered.IPH*
    *   This is kept because it might very well impact what the user
        does next, since the UI will look different than for when it
        is not triggered. In addition, this happens very seldom, so
        the chances of this swamping the dashboards should be small.

The following are marked as not_user_triggered:
*   InProductHelp.NotifyEvent.IPH*
    *   This might be a user action, but if a feature cares about that,
        they should add their own specific action.
*   InProductHelp.ShouldTriggerHelpUI.IPH*
    *   This is very often invoked, but is often a by-product of other
        actions.
*   InProductHelp.ShouldTriggerHelpUIResult.NotTriggered.IPH*
    *   This is recorded around the same time as the
        ShouldTriggerHelpUI, and is also typically a by-product.
*   InProductHelp.ShouldTriggerHelpUIResult.WouldHaveTriggered.IPH*
    *   This is recorded around the same time as the
        ShouldTriggerHelpUI, and is also typically a by-product. It is
        similar to the .Triggered version, but it does not have any
        effect on what the user sees.
