1ce9e26239 fuzz: improve dbwrapper_concurrent_reads performance (Andrew Toth)

Pull request description:

  The recently merged fuzz harness targeting concurrent reads suffers from poor performance and memory leaks (https://github.com/bitcoin/bitcoin/pull/34866#issuecomment-4614323925).

  Fix this by
  - using a global thread pool instead of a local one per iteration
  - reduce thread count to 8 from 16
  - use a std::map oracle to check results inline instead of reading from the db to get a baseline and storing results
