win32.c: conversion to WCHAR

Browse source 
* win32/win32.c (rb_w32_write_console): use MultiByteToWideChar() for
  the last step of conversion to WCHAR, to get rid of warnings from
  rb_enc_find() in miniruby.  [ruby-dev:47584] [Bug #8733]

* win32/win32.c (wstr_to_mbstr, mbstr_to_wstr): fix wrong trimming.
WideCharToMultiByte() and MultiByteToWideChar() do not count
