[Android] Use correctly-scaled icons for keyboard accessory

With this CL, the keyboard accessory controller fetches icons using
GetRawFaviconForPageURL with the desired size in pixels which results
in sharp favicons that scale with Android UI elements.

Before this CL, |GetFaviconImageForPageUrl| was used which assumes the
default size (16dp, as opposed to 20dp) for icons and doesn't provide
scale representation which are suitable for hdpi scales of mobile icons.
(The provided scale was 1x to 2x, but modern phones use scales >= 3.5x)
