Remove non-renderable formats in Dawn backend
Remove non-renderable formats in Dawn backend

kABGR_4444 and kBGR_565 don't have a matching wgpu::TextureFormat, so
they should return false in GrColorTypeToDawnFormat(). This was causing
a color type mismatch where GrAtlasManager was trying to use a 565
atlas.
