IndexedDB: Pass metadata in to IDBOpenDBRequest.onUpgradeNeeded/onSuccess
https://bugs.webkit.org/show_bug.cgi?id=103920

Reviewed by Dimitri Glazkov.

Source/WebCore:

Update IDBCallbacks::onSuccess and IDBCallbacks::onUpgradeNeeded to
pass through a metadata parameter. While there, remove the unused
IDBTransactionBackendInterface parameter to onUpgradeNeeded.

As this is another step in the IDB refactor, I've simplified future cleanup
work by making the WebKit API code still use the old API. This
will make it possible to outright remove code on the chromium side rather
than another three-step checkin.

No new tests, as this is more refactoring.

(WebCore::IDBCallbacks::onUpgradeNeeded): new method signature.

Source/WebKit/chromium:

Support the new IDBCallbacks::onSuccess and IDBCallbacks::onUpgradeNeeded
while maintaining chromium compatibility by shimming in the old API
in the WebKit side. Future code will clean this up so that it is just a
pass-through as it was before.
