It seems that readOnlyDB was still opened which blocked the temp dir
cleanup.
Also changed the copy dir to be another TempDir instead of manually
creating one.

* Use zeropool.Pool to workaround SA6002
I built a tiny library called https://github.com/colega/zeropool to
workaround the SA6002 staticheck issue.
While searching for the references of that SA6002 staticheck issues on
Github first results was Prometheus itself, with quite a lot of ignores
of it.
This changes the usages of `sync.Pool` to `zeropool.Pool[T]` where a
pointer is not available.
Also added a benchmark for HeadAppender Append/Commit when series
already exist, which is one of the most usual cases IMO, as I didn't find
any.

We need to make sure that `tsdb_errors.NewMulti` handles the errors.Is()
calls properly, like it's done in grafana/dskit.
Also we need to check that `errors.Is(err, context.Canceled)`, not that
`err == context.Canceled`.

Test that blocks are not marked as "compaction failed" during shutdown.
This shouldn't happen but this test currently fails.

We need to be able to identify the errors that a multierror wraps.
Especially in case of `context.Canceled`. This is the same
implementation of that method as we do in github.com/grafana/dskit/multierror

Adds `WALReplayConcurrency` as an option on tsdb `Options` and `HeadOptions`.
If it is not set or set <=0, then `GOMAXPROCS` is used, which matches the previous behaviour.

These benchmarks are all testing things related to what Prometheus does,
so perhaps have some historical interest, but we should not retain them
in the main repo.

`safeChunk` is only obtained from the `headChunkReader.Chunk` call where
the chunk is already fetched and stored with the `safeChunk`. So, when
getting the iterator for the `safeChunk`, we don't need to get the chunk again.
Also removed a couple of unnecessary fields from `safeChunk` as a part of this.

* tsdb: make sharding function a parameter
Instead of relying on `labels.Hash()`, which may change, have the
caller pass in a shard function if required.
For most purposes `tsdb.Options.ShardFunc` is used, but the compactor
may be created independently so `NewLeveledCompactorWithChunkSize` also
takes a shard function parameter.
Regular Prometheus, which does not use block sharding, will have this
parameter as nil.
Rename WithCache functions as WithOptions
Where they now have 2 or more extra parameters.
