IndexedDB: update size to actual disk usage only when estimated increase is bigger than space available
https://bugs.webkit.org/show_bug.cgi?id=201957

Reviewed by Youenn Fablet.

For better performance.

Covered by existing tests.

* Modules/indexeddb/server/IDBServer.cpp:
(WebCore::IDBServer::IDBServer::QuotaUser::resetSpaceUsed): m_estimatedSpaceIncrease will be updated when task
is finished, so no need to clear it when doing reset.
(WebCore::IDBServer::IDBServer::QuotaUser::computeSpaceUsed):
* Modules/indexeddb/server/IDBServer.h:

* Modules/indexeddb/server/UniqueIDBDatabase.cpp: instead of reading file size after each task, just add the
task size to known usage and get an estimated usage.

* Modules/indexeddb/server/UniqueIDBDatabase.h:

* storage/StorageQuotaManager.cpp: use m_state to decide what action to take on next request. Previously when a
request asked for size bigger than space available, we would go to ask for more space directly. Now because IDB
can be reporting estimated usage, we first ask IDB to compute its actual disk usage and ask for more space if
actual space available is smaller than requested size.
