indexeddb: remove unneeded includes from IndexedDBContextImpl

These includes will not be valid when idb moves to the storage service.
Additionally, the size is not used as in the web ui so it is safe to
save it as a double instead of a formatted string.  (base::Value does
not support int64_t.)  It could also be potentially removed in the
future.
