### Summary

I'm in the middle of writing some Python commands around a bunch of playbooks I have, one of the commands interacts with some YAML files that potentially include Ansible Vault encrypted strings and generating passwords so I'm shortcutting and importing the various classes and functions from the `ansible` package for use in my own code. 

One command imports `ansible.utils.encrypt:random_password` then eventually calls `os.execlp`. When the exec call happens I then get a warning from Python:

```
.../3.11.4/lib/python3.11/multiprocessing/resource_tracker.py:224: UserWarning: resource_tracker: There appear to be 1 leaked semaphore objects to clean up at shutdown
  warnings.warn('resource_tracker: There appear to be %d '
```

I managed to track it down the culprit to this object: https://github.com/ansible/ansible/blob/devel/lib/ansible/utils/encrypt.py#L46
which after a quick search no longer appears to be used anywhere.

I've updated my code with the following to get rid of the issue. Ideally this lock is either removed or relocated out of the global scope.

```
            import ansible.utils.encrypt
            del ansible.utils.encrypt._LOCK
```

### Issue Type

Bug Report

### Component Name

ansible utils

### Ansible Version

```console
$ ansible --version
ansible [core 2.15.3]
  config file = .../ansible.cfg
  configured module search path = ['~/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = .../lib/python3.11/site-packages/ansible
  ansible collection location = ~/.ansible/collections:/usr/share/ansible/collections
  executable location = .../bin/ansible
  python version = 3.11.4 (main, Aug 31 2023, 14:29:13) [Clang 14.0.3 (clang-1403.0.22.14.1)] (.../bin/python3.11)
  jinja version = 3.1.2
  libyaml = True
```


### Configuration

```console
# if using a version older than ansible-core 2.12 you should omit the '-t all'
$ ansible-config dump --only-changed -t all
CONFIG_FILE() = ./ansible.cfg
DEFAULT_FILTER_PLUGIN_PATH(./ansible.cfg) = ['./ansible/filters']
DEFAULT_ROLES_PATH(/opt/dev/superna/seed/ansible.cfg) = ['./ansible/roles']
EDITOR(env: EDITOR) = mvim -f
```


### OS / Environment

macOS 13.4.1

### Steps to Reproduce

```python
import os
import ansible.utils.encrypt

os.execlp('true', 'true')
```


### Expected Results

Expected no warnings.

### Actual Results

```console
.../lib/python3.11/multiprocessing/resource_tracker.py:224: UserWarning: resource_tracker: There appear to be 1 leaked semaphore objects to clean up at shutdown
  warnings.warn('resource_tracker: There appear to be %d
```
