processor: Add storage for virtual tracks

Adds an indirection for virtual tracks (incl. async event tracks),
so that we can also store a upid with process-scope async tracks.

The new virtual tracks storage is designed for compatibility with a
more generic "tracks" table (track_id column), but for now, we'll use
track_id == index into vtracks.

Also updates proto & fuchsia parsers to store async events with track
references.

The vtracks table is not yet exposed via SQL.
