tsdb(wal): st-per-sample for histograms initial code and benchmarks (#18221) 
Implements ST for Histograms and Float Histograms (and their custom bucket cousins) in WAL. New tests, new benchmarks.

Part of https://github.com/prometheus/prometheus/issues/17790

```release-notes
[CHANGE] Adds Start Time value to all WAL Histogram samples in memory, and therefore may increase memory usage.
```
