Remove support for deprecated kDontClipToLayer_SaveLayerFlag

This removes the conditional behavior based on #defines, and the private
flag definitions. It removes GMs and updates tests that tested the
feature. Follow-up CLs will go through and simplify the internals of
SkCanvas to take advantage of this support removal.
