Add StringOutputBuffer class.

This CL adds a new helper class used to store very large string
output efficiently in memory, while allowing it to be written to
a file, or compared with an existing file's content.

This will be used in future CLs that will speed up and reduce the
RAM usage of some operations like the ones handling --ide=json or
-export-compile-command.

+ Add FileWriter class to encapsulate the Windows-specific
  creation logic required to work-around limitations of
  base::WriteFile()
