Move LineManifold and SphereManifold into their own headers.

Previously they were defined in manifold.h but their implementations
were in the internal directory and to prevent circular dependencies
the implementation headers were pushed to the bottom of manifold.h

This started out as one header and has become progressively worse
as more manifolds are templated.

This change moves the two manifolds into their own headers which
also contain their implementations.
