[Icons NTP] Add chrome://large-icon host, which resizes icon and renders fallback.

The chrome://large-icon endpoint is meant to serve (square) large icons
to the NTP to replace thumbnails. If icon is available, it is resized
first. Otherwise a fallback of the requested size is returned. Therefore
a custom NTP should always gets an image back, and cannot deduce whether
user has visited a site by examining icon presence or icon size.
