Assert text passed to canvas is initialized.

A new fuzzer appears to be complaining about using uninitialized glyph
ids. These uninitilized glyph ids appear to be comming from far up the
stack, but they don't actually get used until much later. If Skia is
passed uninitialized memory in a draw call it will of course eventually
need to use it and be blamed when it does. This change will make it
obvious if the issue is up stack from Skia.
