Original Review: https://codereview.chromium.org/113363004/

Current PPB_FileRef.MakeDirectory returns PP_OK if a directory exists on
the given path. This makes it difficult to create POSIX compatible API on
top of PPAPI.

This change introduces new PPB_FileRef.MakeDirectory as dev channel API.
That makes a new directory according to the given PP_MakeDirectoryFlags
values. The flags provide exclusive operation option. If exclusive flag
is specified and a directory exists on the given path, the function fails
and returns PP_ERROR_FILEEXISTS.
