Merge #20458: test: add is_bdb_compiled helper

b87caf10b5 test: add is_bdb_compiled helper (Sjors Provoost)

Pull request description:

  Followup for #20202, needed by #16546.

  Allow the functional test suite to skip tests that require BDB, as well as introduce specific logic to handle whether BDB support is enabled or not. It follows the same pattern as `skip_if_no_sqlite` and `is_sqlite_compiled`.
