* src/winfonts/winfnt.c (fnt_face_get_dll_font): Return error

Browse Source 
FNT_Err_Invalid_File_Format if file format was recognized but
the file doesn't contain any FNT(NE) or RT_FONT(PE) resources.
Add verbose debug logs to make it easier to debug failing load
attempts.
(FNT_Face_Init): A single FNT font can't contain more than 1 face,
so return an error if requested face index is > 0.
Do not do further attempt to load fonts if a previous attempt has
failed but returned error FNT_Err_Invalid_File_Format, i.e., the
file format has been recognized but no fonts found in the file.
