First pass at font cache refactor: Create an atlas manager per texture

First pass at font cache refactor: Create an atlas manager per texture

created per-texture. This is the first step in allowing us to create
Atlases of other types (e.g., combine small icons into one big texture).

Not for this CL, but just wondering if we really need a separate MaskFormat enum
at all.

Yup, the next CL will pull use of that out of the Atlas code and make it
general.
