[stdlib] Add monitor contention helper functions

Parsed all the monitor contention slices into two tables:
1. monitor_contention: Contains the raw parsed information with an
additional column |binder_reply_id| for correlating contention to
binder txns
2. monitor_contention_chain: Contains #1 and an additional column
|parent_id| to represent the graph of contentions

In addition, exposed useful ANDROID_EXTRACT_MONITOR_CONTENTION_*
helper functions for extracting individual columns from a slice.

Test: tools/diff_test_trace_processor.py out/android/trace_processor_shell
