GTK: Match link colors.

- Realize our fake window in the GtkThemeProvider so we can access the style
  properties.
- Make sure we don't generate the markup for a GtkChromeLinkButton until
  after it is realized.
- Make sure GtkChromeLinkButton responds to system wide style theme changes.

BUG=43850
TEST=Open up chrome to the NTP with an empty bookmark bar in GTK+ theme mode. The links on the NTP should match the GTK+ link color, and so should the import bookmark link in the bookmark bar. Change your GTK+ theme to one with a different link color. The NTP and import bookmark link should change to the new color.
