### Description
Addresses #12704. Below is the comment that inspired this
([link](https://github.com/apache/lucene/pull/12633#discussion_r1366847986)),
```
Instead, we should multiply with the gold constant BitMixer#PHI_C64 (make it
public).
This really makes a difference in the evenness of the value distribution.
This is one of the secrets of the HPPC hashing. By applying this, we get
multiple advantages:
* lookup should be improved (less hash collision)
* we can try to rehash at 3/4 occupancy because the performance should not
be impacted until this point.
* in case of hash collision, we can lookup linearly with a pos = pos + 1
instead of quadratic probe (lines 95 and 327); this may avoid some mem cache
miss.
*
(same for the other hash method)
```
