Interpolate loading progress in tab animation

Instead of skipping to the new load-progress value as it arrives,
interpolate to it. This results in a smoother animation as the
load-progress callbacks can be fairly sparse (and jump from 20% to 80%
for instance).

Drives animations off of the same timer that is used for the throbbing
state. This will hopefully address a performance regression as the
throbbing timer, progress fade-out animation and favicon fade-in
animation were all scheduling separate high-frequency repainting of the
tab icon.
