[stdlib]: Add an interval flatten macro

This can be used to flatten any rooted hierarchy of intervals to
a new set of intervals showing the leaves. E.g flatten a slice stack
to self time.

Update the slice flattening module to use this.

Test: tools/diff_test_trace_processor.py out/android/trace_processor_shell --name-filter '.*intervals_flatten.*'
