Compress mini-debug-info in small chunks.

Compress the mini-debug-info in small independent parts.
This still results in standard compressed data stream.
However, by dividing into chunks, the compressed data
can be random accessed - that is, it makes it possible
to decompressed only the data that is needed.

This increases size of .oat files by 1.2%.
