This removes the stringlabels build tag, makes that implementation the default one, and moves the old labels implementation under the slicelabels build tag.
Fixes#16064.

This test consistently fails missing ~10 series.
If it doesn't fail on your machine, just increase totalSeries, that's
how race conditions work.

* Remove experimental out-of-order native histogram flag
This feature has been available in Prometheus since September 2024,
and has no known issues. Therefore proposing to remove the flag
entirely and always have it on. Note that there are still two
settings that need to be configured (out-of-order time window > 0
and native histograms enabled) for this feature to work.

Renames the head's deleted map to walExpiries, and creates entries for any
duplicate series records encountered during WAL replay, with the expiry set
to the highest current WAL segment number. Any subsequent WAL
checkpoints will see the duplicate series entry in the walExpiries map, and
keep the series record until the last WAL segment that could contain its
samples is deleted.
Other considerations:
WBL: series records aren't written to the WBL, so there are no duplicates to deal with
agent mode: has its own WAL replay logic that handles duplicate series records differently, and is outside the scope of this PR
'defer' only runs at the end of the function, so explicitly close the
querier after we finish with it. Also check it didn't error.

This enables it to take advantage of a more compact data structure
since all postings are known to be `*ListPostings`.
Remove the `Get` member which was not used for anything else, and fix up
tests.

When handling recoded histogram chunks the min time of the chunk is
updated by mistake. It should only update when the chunk is completely
new.

Two Appenders race when creating a series with a native histogram

This was part of #14525 which was reverted.
I still think that having this benchmark committed in to the repo is
useful.

* Fix appendable: check whether last val was a histogram
When appending a float, we were checking whether lastValue was equal to
current value, but we didn't check whether last value was a float value.
