IndexedDB: Allow createIndex/createObjectStore to be asynchronous
https://bugs.webkit.org/show_bug.cgi?id=106377

Reviewed by Tony Chang.

Source/WebCore:

Migrate implementations of createIndex/deleteIndex,
createObjectStore/deleteObjectStore over to IDBDatabaseBackendImpl,
so that they can be asynchronous in multi-process ports.

Has the side effect of removing the last consumers of
IDBIndexBackendImpl and IDBObjectStoreBackendImpl. The former
is removed complete and the latter becomes a temporary namespace
pending a further more mechanical code shuffle.

A key refactoring effect is that the IDBDatabaseBackendImpl
now contains the authoritative IDBDatabaseMetadata hierarchy,
and updates to it are consolidated in one place rather than
scattered across a parallel object tree.

No new tests as this is just refactoring.

Remove this test as it makes no sense once the objectstore/index
hierarchy is gone.
