Clear-Site-Data: clients uncontrolled by service workers after storage directive (#19132)

Adds a failing test, asserting that pages actively controlled by a service worker become uncontrolled after the Clear-Site-Data storage directive.

We agreed on this behavior in a spec issue and confirmed the need for this test at the TPAC Service Workers F2F.
