[C++] Remove Deprecated WriteableFile warning

[asfimport]

Current version is 0.14.1. As per comment, deprecated WriteableFile should be removed. 

 

// TODO(kszucs): remove this after 0.13
#ifndef _MSC_VER
using WriteableFile ARROW_DEPRECATED("Use WritableFile") = WritableFile;
using ReadableFileInterface ARROW_DEPRECATED("Use RandomAccessFile") = RandomAccessFile;
#else
// MSVC does not like using ARROW_DEPRECATED with using declarations
using WriteableFile = WritableFile;
using ReadableFileInterface = RandomAccessFile;
#endif

I think this was addressed by e41ad0d2 which should make it into the 0.15 release.
