[path] Separate the approx. bounds into 3 distinct functions

Based on feedback from Jeff Muizelaar, there is a case for a very quick
and dirty extents approximation based solely on the curve control points
(for example when computing the clip intersect rectangle of a path) and
by moving the stroke extension into a core function we can clean up the
interface for all users, and centralise the logic of approximating the
stroke extents.
