Simon Glass 430e1676a7 video: Add commands to list and change fonts
Add a new 'font' command which allows the fonts to be listed as well as
selecting a different font and size.

Allow the test to run on sandbox, where multiple font/size combinations
are supported, as well as sandbox_flattree, where they are not.
