Merge bitcoin/bitcoin#24670: test: move-only: Move all generate* tests to a single file

0000ff0 test: move-only: Move all generate* tests to a single file (MarcoFalke)

Pull request description:

  Seems a bit overkill to spread tests for the `generate*` methods over several files. Combining them into a single file has also a nice side-effect of requiring less node (re)starts, which are expensive in valgrind.
