perf annotate: Split branch stack cycles info from 'struct annotation'
The cycles info is only meaningful when sample has branch stacks. To
save the memory for normal cases, move those fields to a new 'struct
annotated_branch' and dynamically allocate it when needed. Also move
cycles_hist from annotated_source as it's related here.
