go.*,widget: add initial emoji rendering benchmarks

This commit upgrades our version of eliasnaur.com/font to include a color
emoji font and uses that to benchmark displaying large quantities of emoji.
As expected, this is very slow when the strings change frequently, and uses
silly amounts of memory. Future commits will work to improve this.
