adb: win32: remove widen()/narrow() in favor of UTF8ToWide()/WideToUTF8()
Now that we have a more standardized API (also available in Chromium),
switch to it. Another benefit is real error handling instead of just
killing the process on invalid Unicode.
Make UTF8ToWide()/WideToUTF8() set errno to EILSEQ on bad input. This is
the same error code that wcsrtombs(3) uses.
Update the unittest to check for EILSEQ.
