Prajjwal 50a79c6af8 LibWeb: Change SessionHistoryTraversalQueue to use Promises ...

If multiple cross-document navigations are queued on
SessionHistoryTraversalQueue, running the next entry before the current
document load is finished may result in a deadlock. If the new document
has a navigable element of its own, it will append steps to SHTQ and
hang in nested spin_until.
This change uses promises to ensure that the current document loads
before the next entry is executed.

Fixes timeouts in the imported tests.
