Add contexts to index writer to fix test races.
...
With recent speed improvements to populate block,
the cancellation test now fails regularly on CI.
Use contexts to get the index writer to shut down
much faster, and that allows us to make the cancellation
test faster too.

Coalesce series reads where we can.
...
When compacting rather than doing a read of all
series in the index per label name, do many at once
but only when it won't use (much) more ram than writing the
special all index does.

Don't buffer up tables in memory on compaction. ( #6422 )
...
We can instead write it as we go, and then go back and write in the
length at the end.
Also fix the compaction benchmark, which indicates no changes.
For the benchmark, this brings maximum memory usage of the buffers
from ~200kB down to 128B.
