test: random particle generator serialization

[tjhei]

part of #7099 because checkpointing is broken due to random number generators. This test fails without a fix such as proposed #7099 or #7240

Test written by AI.

FYI @bangerth

[bangerth]

Let's hold off on this then for now.

[tjhei]

waiting for #7245

[bangerth]

Actually, to the successor of #7245 that isn't written yet.

[bangerth]

Can you rebase this now?

[tjhei]

Rebased. Let's see what happens.

[bangerth]

Well, it fails:

Alright, I got it to work. It is worth noting that this is seems to be the first checkpointing test with >1 MPI rank. @bangerth
