Merge bitcoin/bitcoin#28065: fuzz: Flatten all FUZZ_TARGET macros into one

fa6dfaaf45bde465969fa7d8fa6b6574a497a6ca scripted-diff: Use new FUZZ_TARGET macro everywhere (MarcoFalke)
fa36ad8b091c70190491280dcf0794e94e34a9ed fuzz: Accept options in FUZZ_TARGET macro (MarcoFalke)

Pull request description:

  The `FUZZ_TARGET` macros have many issues:
  * The developer will have to pick the right macro to pass the wanted option.
  * Adding a new option requires doubling the number of existing macros in the worst case.

  Fix all issues by using only a single macro.

  This refactor does not change behavior.
