tracing: Add kprobe event command generation functions
Add functions used to generate kprobe event commands, built on top of
the dynevent_cmd interface.
kprobe_event_gen_cmd_start() is used to create a kprobe event command
using a variable arg list, and kretprobe_event_gen_cmd_start() does
the same for kretprobe event commands. kprobe_event_add_fields() can
be used to add single fields one by one or as a group. Once all
desired fields are added, kprobe_event_gen_cmd_end() or
kretprobe_event_gen_cmd_end() respectively are used to actually
execute the command and create the event.
