Bug 1156742 Part 24: Add new Recorded event to record font data. r=bas

We create and destroy ScaledFonts for every piece of text we write.
That causes a huge amount of duplicated data within the recording.
This splits out the recording of the font data itself from the ScaledFont.
The key generated to determine uniqueness could probably be fairly easily faked, but for our purposes that doesn't matter.
