Failing clustering helpers test

[aprokop]

In #1034, an update to HIP 6.2 resulted in two failed tests, ArborX_Test_DetailsClusteringHelpers.exe and ArborX_Test_Clustering.

I tried to reproduce the failure on Frontier, and I actually can't make the helper test pass at all. I tried these combinations:

ArborX version	Kokkos version	HIP version
master	4.4.1	6.2.3
master	4.4.1	6.1 3
master	4.3.1	6.1.3
master	4.3.1	5.7.1
1.7	4.3.1	5.7.1
1.6	4.3.1	5.7.1
1.5	4.3.1	5.7.1

No idea what's going on at the moment. It results in memory violation withing the Boruvka loop.
