Introduce SharedDictionaryWriterOnDisk

This CL introduces SharedDictionaryWriterOnDisk class which stores the
binary of dictionary as an entry of SharedDictionaryDiskCache. Its
FinishCallback is called when the entire dictionary binary has been
stored to the disk cache, or when an error occurs. This class handles
zero-sized data as an error.

Currently, SharedDictionaryWriterInMemory's FinishCallback can be called
with zero-sized data. To make the behavior consistent, this CL also
modifies SharedDictionaryWriterInMemory to call FinishCallback with an
error when no data has been written.

Also this CL changes SharedDictionaryDiskCache to support using mocked
Disk Cache backend for testing
