perf(chunkenc): intern the custom values for native histograms 
The custom values are the "le" bucket boundaries of native histograms
with custom buckets. They are never modified. It is ok to not copy them
when iterating a chunk, just reference them.

If we will ever have a function that modifies the custom values, like
'trim' for example. That function will have to make a copy on write.
