Add Atlas Text interface for rendering SDF glyphs.
This new API is built upon SDF text atlas code from the GPU backend. Unlike using the GPU
backend to draw text, this set of interfaces allows the client to render the SDF glyphs. The
client issues text draws to potentially multiple targets and then the client flushes. The
client then gets commands from Skia with data to put into a texture atlas and vertices to
draw that reference the texture. The client is responsible for creating the texture, uploading
the SDF data to the texture, and drawing the vertices provided by Skia.
