kernel: add requirement Ids to implementation
kernel: add requirement Ids to implementation

Add requirement ID place holders based on APIS. The requirements will
appear as a list in doxygen documentation. The IDs will be expanded with
more details somewhere else, probably a requirement catalog on GH or
some other requirement management tool. This is still TBD.
