This PR adds an optional field to the existing `Xoshiro` struct to be able to faithfully copy the task-local RNG state. Fixes #51255 Redo of #51271 Background context: #49110 added an additional state to the task-local RNG. However, before this PR `copy(default_rng())` did not include this extra state, causing subtle errors in `Test` where `copy(default_rng())` is assumed to contain the full task-local RNG state.
