Make QFSFileEngine & QFileInfo use the new filesystemengine on Windows

QFSFileEngine now uses the QFileSystemEngine static functions to
implement most of the file system related quries. All the Win32 specific
code is now moved from the QFSFileEngine to QFileSystemEngine. This
implements all the fillMetaData and filename query functions. These new
functions behave exactly like their previous implementations in
QFSFileEngine. Following optimizations are done with this.

* GetFileAttributesEx() instead of GetFileAttibutes().
* GetFileInformationByHandle() instead of POSIX  functions.
