Add MemoryFileStream[Reader/Writer].

MemoryFileStreamReader and MemoryFileStreamWriter classes are added to
read/write from memory files. When a new file stream reader/writer is
asked to be created, file system backend is queried if the operating is
in incognito mode or regular mode and if it's incognito, the
MemoryFileStream* ones are created instead of LocalFileStream* ones.

The change is part of the following design doc:
