DEV: Introduce Theme#get_setting (#24032)
Why this change?

Currently, we do not have a method to easily retrieve a theme setting's
value on the server side. Such a method can be useful in the test
environment where we need to retrieve the theme's setting and use its
value in assertions.

What does this change do?

This change introduces the `Theme#get_setting` instance method.
