perf ui annotate browser: Allow toggling addr offset view

The lines in objdump have this format:

    ffffffff8126543f:       jne    ffffffff81265494 <__list_del_entry+0x84>
<SNIP>
    ffffffff81265494:       mov    %rdi,%rcx

Since we now have objdump_line allowing tools to print the offset
independently from the rest of the line, allow toggling a view where
just offsets from the start of the function are shown:

     2f:       jne    ffffffff81265494 <__list_del_entry+0x84>
<SNIP>
     84:       mov    %rdi,%rcx

The offset view will be the default as soon as operations that deal with
offsets in a function are handled accodringly, i.e. in offset view the
above will become:

     2f:       jne    __list_del_entry+0x84
<SNIP>
     84:       mov    %rdi,%rcx

And then a follow up patch will allow navigating thru jumps, just like
we handle callq instructions.
