Adds HCI support for LE CS subevent result continue event and the reassembly logic for the partial results. When subevent results are completed or the subevent is aborted, the user callback is invoked with a buffer pointing to the HCI event buffer, so no copy is done. When subevent results are incomplete, then a reassembly buffer is allocated from a fixed sized pool. This buffer is used for the reassembling of the subevent result containing all of the step data, which is then passed to the user via the callback. kconfigs have been added to set the size and the count of the reassembly buffer.
