Support multiple data-wp-on-window or data-wp-on-document directive with the same event

[DAreRodz]

Currently, both data-wp-on-window and data-wp-on-document can't be used more than once on the same element and for the same event type. For example, the following code won't work, because browsers don't support duplicated attributes (data-wp-on-window--click in this case).

<div
  data-wp-interactive="test/on-window"
  data-wp-context='{ "clickCount": 0, "isToggled": false }'
  data-wp-on-window--click="actions.countClick"
  data-wp-on-window--click="actions.toggle"
>Click me!</button>

To fix this, we could use a similar approach to the one in #60661 for data-wp-on, i.e., allowing appending an ID to differentiate multiple directives with the same event.

I'll take a look at this one.
