Widgets: Make sure `WP_Widget` constructor creates a correct `classname` value for a namespaced widget class.

This reverts the changes to `id_base` from [50953] due to backward compatibility concerns, and instead focuses on the `id` and `class` attributes specifically.

With this change, any backslashes in the `id` or `class` attributes for a namespaced widget class are converted to underscores, making it easier to style the output or target the widget with JavaScript.

Follow-up to [50953].

Fixes #44098.
