trace, documentation: Fix branch profiling location in debugfs
The debugfs interface for branch profiling is through /sys/kernel/debug/tracing/trace_stat/branch_annotated /sys/kernel/debug/tracing/trace_stat/branch_all so update the Kconfig accordingly.

This tracer profiles all the the likely and unlikely macros
