IndexedDB transactions stall when reusing a service worker process without
RunningBoard
https://bugs.webkit.org/show_bug.cgi?id=324058
<rdar://problem/187349702>
Reviewed by Sihui Liu.
Without RunningBoard `ProcessThrottler::didConnectToProcess` is never called so
`ProcessThrottler::currentState` keeps reporting its initial
`ProcessThrottleState::Suspended` value.
When navigation reuses a standalone `ServiceWorker` WebProcess,
`WebProcessProxy::addExistingWebPage` passes that value to
`WebProcessProxy::didChangeThrottleState` to refresh NetworkProcess assertions.
This incorrectly marks the IndexedDB client suspended with no subsequent resume
notification to restart its transactions.
315609@main added the storage suspension notifications and 319873@main made the
scheduler defer queued transactions while the client is suspended.
The incorrect state also affects other readers, including the foreground flag
reported by `WebProcessProxy::didExceedMemoryFootprintThreshold`.
Correct the state at its source rather than making one caller ignore it,
preserving the assertion refresh introduced by 263031@main when a
`ServiceWorker` WebProcess gains a page without changing `ProcessThrottleState`.
