bpf: Add support for tracing_multi link session

Adding support to use session attachment with tracing_multi link.

Adding new BPF_TRACE_FSESSION_MULTI program attach type, that follows
the BPF_TRACE_FSESSION behaviour but on the tracing_multi link.

Such program is called on entry and exit of the attached function
and allows to pass cookie value from entry to exit execution.
