Add granular control over disabled effects.

Currently, we can only wholesale disable effects outside of zen mode.
There are some devices that require long running suppression of features.
Effects disabling was added previously to support this. However, calling
suppression was broken recently on a device where we needed notification
suppression, but not calling suppression.

This CL remedies this problem by adding more granular disabled effects
hints. The NotificationManagerService has been updated to handle these
request types and present ZenModeHelper with a unified map of what should
be suppressed.
