Limit TrackRunInfo.samples allocation size to 150MB.

When trun.sample_count is large, TrackRunInfo.samples may be allocated larger than available memory.
This CL caps that allocation to 150MB, and removes the earlier limit that disallowed two (or more)
zero-sized samples in a row.

This effectively limits the number of samples per trun to 6.5M, which also helps avoid timeouts in
fuzzing. That problem is unlikely to be solved by this CL alone, though.
