Standardize the header comments for friend functions in cord.h

fe61602701be795e54477b0fdbf5ffc1df12a6b7 by Samuel Benzaquen <sbenza@google.com>:
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.
