cc: Simplify raster task completion notification logic

Previously the pixel buffer raster worker pool used a combination of
polling and explicit notifications from the raster worker pool to decide
when to tell the client about the completion of 1) all tasks or 2) the
subset of tasks required for activation. This patch simplifies the logic
by only triggering the notification based on the OnRasterTasksFinished
and OnRasterTasksRequiredForActivationFinished calls from the worker
pool.

Certificate Transparency: If an EV cert has SCTs, those must not be invalid

This change removes the EV status of a certificate if it has SCTs from known
CT logs but all SCTs are invalid (i.e. there's not one valid SCT, and all
other SCTs are from known logs but do not validate).
