Implement %f natively for any input.
It evaluates the input at runtime and allocates stack space accordingly.

This removes a potential fallback into snprintf, improves performance, and removes all memory allocations in this formatting path.

Add a Cord::swap() method.  Many other Abseil types already provide this, but it was missing here.

We already provided a two-argument free function form of `swap()`, but that API is better suited for generic code.  The swap member function is a better API when the types are known.
