MarcoFalke 6dbc9aba0d Merge #17675: tests: Enable tests which are incorrectly skipped when running test_runner.py --usecli
5ac804a9eb0cdbdcff8b50ecfb736f8793cab805 tests: Use a default of supports_cli=True (instead of supports_cli=False) (practicalswift)
993e38a4e2fa66093314b988dfbe459f46aa5864 tests: Mark functional tests not supporting bitcoin-cli (--usecli) as such (practicalswift)

Pull request description:

  Annotate functional tests supporting `bitcoin-cli` (`--usecli`) as such.

  Prior to this commit 74 tests were unnecessarily skipped when running `test_runner.py --usecli`.

  Before [bitcoin original commit stats]:

  ```
  $ test/functional/test_runner.py --usecli > /dev/null 2>&1
  $ echo $?
  0
  $ test/functional/test_runner.py --usecli 2>&1 | cut -f2 -d'|' | \
      grep -E ' (Passed|Skipped) *$' | sort | uniq -c
        9  ✓ Passed
      126  ○ Skipped
  ```

  After [dash numbers]:

  ```
  $ test/functional/test_runner.py --usecli > /dev/null 2>&1
  $ echo $?
  0
  $ test/functional/test_runner.py --usecli 2>&1 | cut -f2 -d'|' | \
      grep -E ' (Passed|Skipped) *$' | sort | uniq -c
       110  ✓ Passed
       51  ○ Skipped
  ```

  Context: `--usecli` was introduced in f6ade9ce1a
