 * Services for procedural implementation of hooks are also registered.

 *  - includes files that contain hooks that are not defined by hook_hook_info

 *    or in .module files

 *  - group_includes files identified by hook_hook_info

 *  - packed_order_operations ordering rules for runtime evaluation

 *

 * The parameter hook_data is processed in HookCollectorKeyValueWritePass and

 * removed automatically.
