localStorage: Flushing unwritten data in Android's ChromiumApplication.
This adds a new StoragePartition::Flush method to flush all unwritten data
for the StoragePartition. At present this only flushes the
DOMStorageContextImpl - not sure if other storage systems require flushing.
Also, included a few headers (as suggested by git cl lint), and fixed a few
typos.
