8ea8833979 swr/resample: move templating parameters to template itself.
It has various benefits such as allowing some refactoring, clarifying
the code in the inclusion part, and making the template understandable
in standalone.

This commit is based on the templating method used by Justin Ruggles for
libavresample.
