Calling `CreateFileW` without making sure that the patname is really
`wchar_t` is a bad idea and can lead to unpredictable overreads. For
Windows CE, we impelemnt the missing API.
Fixes#1098 and !76 again.
* builds/windows/ftsystem.c (FT_Stream_Open): Call `CreateFileA`.
[_WIN32_WCE] (CreateFileA, FileSizeEx): Implement missing interfaces.
Windows handles wchar_t* UTF-16 and char* ANSI (presently UTF-8)
filenames using alternative -A and -W API. We'll try them both
when opening a file. This means that you should not worry about
about conversions.
Fixes#1098 and !76.
* builds/windows/ftsystem.c (FT_Stream_Open): Call alternative
`CreateFile` in the case of failure.
