Brian Salomon 3d6801eeee Add GrGLMakeNativeInterface factory that returns sk_sp<const GrGLInterface>.
Removes the concept of a configurable "default" interface and makes the default
always be the "native" interface.

Also removes unused functions: GrGLInterfaceAddTestDebugMarker and
GrGLInterface::NewClone.

Keeps around legacy GrGLCreateNativeInterface() until clients can be weened.
