  [BOLT] Handle recursive calls as inter-branches in DataAggregator

Align yaml and fdata profiles by applying the same treatment to recursive
calls (direct, indirect, tail). fdata profile increments entry count when
handling recursive calls. Make perf/pre-aggregated perf reader (DataAggregator)
do the same.

Test Plan:
In pre-aggregated-perf.test, add a dummy pre-aggregated branch entry between
an indirect call in `frame_dummy` function and its entry point.
Check that YAML profile gets incremented entry count for this function.
