perf c2c: extract shared data structures into util/c2c.h

Browse source

The function browser belongs in libperf-ui.a, but that archive is also
linked into python/perf.so, where builtin command objects are unavailable.
The browser therefore cannot depend on types or callbacks owned by
builtin-c2c.c.

Move c2c_hists, compute_stats, c2c_hist_entry, and the shared column
formatting definitions from builtin-c2c.c to a new util/c2c.h. Move
c2c_fmt_free() and c2c_fmt_equal() to a new util/c2c.c.

Keep struct perf_c2c, the command instance, and
perf_c2c__browse_cacheline() private to builtin-c2c.c.

No functional change.
