[Android WebView] Only throttle fallback tick

[Android WebView] Only throttle fallback tick

When throttling, either when paused or when in background, only throttle
fallback tick. There are apps relying on the fact that invalidates are
not throttled when paused. When in background, framework should take
care of not calling back with draw for invalidates.

Looks like we should be thinking about ways to wrap some focused unit tests
around EnsureContinuousInvalidation() to catch any regressions in this lot.
