4275195606 De-duplicate add_coin methods to a test util helper (Jon Atack)
9d92c3d7f4 Create InsecureRandMoneyAmount() test util helper (Jon Atack)
81f5ade2a3 Move random test util code from setup_common to random (Jon Atack)
Pull request description:
- Move random test utilities from `setup_common` to a new `random` file, as many tests don't use this code.
- Create a helper to generate semi-random CAmounts up to `MONEY_RANGE` rather than only uint32, and use the helper in the unit tests.
- De-duplicate a shared `add_coin` method by extracting it to a `coins` test utility.

Pull request description:
This is an alternative to #25354 (by my benchmarking, somewhat faster), subsumes #25712, and adds additional test vectors.
It separates the multiple-of-64-bytes-only "core" logic (which becomes simpler) from a layer around which performs caching/slicing to support arbitrary byte amounts. Both have their uses (in particular, the MuHash3072 code can benefit from multiple-of-64-bytes assumptions), plus the separation results in more readable code. Also, since FastRandomContext effectively had its own (more naive) caching on top of ChaCha20, that can be dropped in favor of ChaCha20's new built-in caching.
I thought about rebasing #25712 on top of this, but the changes before are fairly extensive, so redid it instead.

files share the same purpose, and we shouldn't have wallet code
inside the test directory.
This later is needed to use wallet util functions in the bench
and test binaries without be forced to duplicate them.
This was used to, in effect, manually emulate --start-group/--end-group.
However, we can just order the libraries correctly and avoid specifying
libraries multiple times on the link line.
Note: lld (not ld.bfd) knows how to resolve out-of-order references and
doesn't seem to need the reodering
