pipeline: lazily get ctx in _get_layer

Browse Source 
We only need a ctx pointer if we need to refer to the default_layer_x
layers to copy as templates so only call  _cogl_context_get_default()
once we need to copy a template. _cogl_context_get_default() was
starting to show up in profiles and this was the main cause.
