Rework the J1939 and ISO TP feature enabling logic in config.cmake to: - define WITH_FEATURE_J1939 and WITH_FEATURE_ISOTP to default to off, thus requiring explicit enabling. This is safer than making assumptions based solely on the presence of the headers at build time. - honor WITH_FEATURE_* definitions given on the cmake command-line; the checks for header presence only over-ride an "ON" value if the required header is not present.

+## Enable support at build time
+
+To enable J1939 support, the binding must be built with -DWITH_FEATURE_J1939=ON.
+If using the autobuild script, add CONFIGURE_ARGS="-DWITH_FEATURE_J1939=ON" to the command used.
