trace_processor: add memory events

This CL adds the parsing and storing of the following events into
the counters table:
rss_stat
ion_heap_grow
ion_heap_shrink

It also
- fixes the inconsistent naming in the refType enum
- renames sched tracker to better reflect it's purpose
- remove pre-computed deltas because they can be ambiguous
