perf annotate-data: Show offset and size in hex

It'd be better to have them in hex to check cacheline alignment.

 Percent     offset       size  field
  100.00          0      0x1c0  struct cfs_rq    {
    0.00          0       0x10      struct load_weight  load {
    0.00          0        0x8          long unsigned int       weight;
    0.00        0x8        0x4          u32     inv_weight;
                                    };
    0.00       0x10        0x4      unsigned int        nr_running;
   14.56       0x14        0x4      unsigned int        h_nr_running;
    0.00       0x18        0x4      unsigned int        idle_nr_running;
    0.00       0x1c        0x4      unsigned int        idle_h_nr_running;
  ...

Committer notes:

Justification from Namhyung when asked about why it would be "better":

Cache line sizes are power of 2 so it'd be natural to use hex and
check whether an offset is in the same boundary.  Also 'perf annotate'
shows instruction offsets in hex.

I can add an option and/or a config if you want.
