[roll pigweed] third_party: Copybara script for importing fit::function from Fuchsia

pw::Function's implementation will be replaced with fit::function from
Fuchsia. fit::function is more advanced than pw::Function and supports
features like dynamic allocation and sharing callables between multiple
fit::function instances.

This copy.bara.sky script will be used to import the fit::function
sources and transform them as needed.
