The Skia change here https://skia.googlesource.com/skia.git/+/681a68d035103c5b93f646f4ccf38645f1852f8c will disallow redefinition of builtin functions, which
saturatein the ink sparkle shader does. This PR simply inlines the function. A real fix that namespaces user defined functions in impellerc will come later.
