perf annotate: Allow showing offsets in more than just jump targets

Jesper wanted to see offsets at callq sites when doing some performance
investigation related to retpolines, so save him some time by providing
an 'struct annotation_options' to control where offsets should appear:
just on jump targets? That + call instructions? All?

This puts in place the logic to show the offsets, now we need to wire
this up in the TUI browser (next patch) and on the 'perf annotate --stdio2"
interface, where we need a more general mechanism to setup the
'annotation_options' struct from the command line.
