Hal Canary 56df7910b0 experimental/minimal_ios_mtl_skia_app: clean up ... Motivation: make is easier to add multiple views sharing a GrContext. - Split configure_mtk_view() from to_context() - AppViewDelegate no longer owns GrContext - Split out config_paint() and draw_example() fns to delineate example code from useful code. - AppViewDelegate no longer responsible for initializing itself. - AppViewController owns MTLDevice and GrContext.
