sessionStorage entries are identified via their associated origins and removed across all browsing contexts. This brings sessionStorage in line with cookies, which were already handled by the API. Both public and private browsing contexts are included in the clearing operation. The necessary support has been added to the storage crate to clear WebStorage data. Testing: A new integration test has been added. Signed-off-by: Jan Varga <jvarga@igalia.com>
