819d03b932134ee91df3b0fe98a481a331ce57bf refactor: took out unused member functions (Zero)
ed69213c2b2a99023bdee5168614cb8b71990f5f build: enable unused member function diagnostic (Zero)

Pull request description:

  This PR enables the `-Wunused-member-function` compiler diagnostic, as discussed in #19702.

  > **Notice**: The `unused-member-function` diagnostic is only available on clang. Therefore, clang should be used to test this PR.

  - [x] Include the `-Wunused-member-function`diagnostic in `./configure.ac`. (ed69213c2b2a99023bdee5168614cb8b71990f5f)
  - [x] Resolve the reported warnings. (819d03b932134ee91df3b0fe98a481a331ce57bf)

  Currently, enabling this flag no longer reports the following warnings:

  > **Note**: output from `make 2>&1 | grep "warning: unused member function" | sort | uniq -c`

  ```
  1 index/blockfilterindex.cpp:54:5: warning: unused member function 'DBHeightKey' [-Wunused-member-function]
  2 script/bitcoinconsensus.cpp:50:9: warning: unused member function 'GetType' [-Wunused-member-function]
  1 test/util_tests.cpp:1975:14: warning: unused member function 'operator=' [-Wunused-member-function]
  ```

  All tests have passed locally (from `make check` & `src/test/test_bitcoin`).

  This PR closes #19702.
