Layers implementation in GL.

- add textures management code for layers in TilesManager
- add the layers drawing GL code
- modify BaseLayerAndroid::drawGL() to paint the layers
- modify TexturesGenerator to process layers painting requests
Note: some further refactoring (when getting rid of SkLayer as a base
class) will let us remove some redudant function, e.g.
setAnchorPoint/setAnchorPointZ (bug:3292285)
