The previous CLs have removed the last significant differences between SkSL::String and std::string. This CL removes SkSL::String entirely and replaces it with std::string throughout the code. Apologies for the very long CL, but I have done my best to make it as simple and reviewable as possible. The vast majority of changes are simple replacement of `SkSL::String` with `std::string`. In the rare spots where code is moved from one place to another, it is logically unchanged.
