Currently, several components will trigger their `onClick` twice if you
click on their labels.

After this fix, the affected components will only trigger `onClick` once

## Other information

<!-- Any other information that is important to this PR such as
screenshots of how the component looks before and after the change. -->

The affected components are:
- Checkbox
- Select
- Textarea
- Toggle
- Input

I also tested radio and range but could not reproduce the issue for
them.

Note that two of the components, checkbox and toggle, had to have
special implementations for both their test and fix because of how the
host component acts as the component for accessibility purposes.

Current dev build: `8.5.7-dev.11746044124.147aab6c`
