target: further shrink Jim-awareness

Don't include <helper/jim.h> from target.h ... not everything
which touches targets needs to be able to talk to Jim.  Plus,
most files include this header by another path.

Also, switch the affected files to use the classic sequence
for #included files:  all <framework/headers.h> first, then
the "local_headers.h".  This helps prevent growth of problematic
layering, by minimizing entanglement.
