TraceProcessor: add ninja log parsing

Adds a parser for ninja build logs. This is the
moral equivalent of https://github.com/nico/ninjatracing.
This works only as long as ninja doesn't hit recompaction.
The log seems to stop making sense after re-compaction because
it becomes impossible to reconstruct the boundaries of
each build invocation.
I eye-balled this vs ninjatracing on the same trace and
the results seem to make sense.
