[ros-diffs] [hpoussin] 17162: Implement SetupGetInfFileListW and SetupGetInfInformationW

Implement SetupGetInfFileListW and SetupGetInfInformationW
Inf file parser now accept UNICODE files with FF FE header
Return required buffer size when buffer is too small in
SetupGetLineTextA/W, SetupGetStringFieldA/W
