0031582: Configuration, CMake - OCCT fails to build with VTK 9.0

Handle "VTK::" prefix instead of "vtk" used by previous VTK versions for targets.
Corrected unexpected location of endif() and broken indentation.
Obsolete $VTK_USE_FILE is no more included (basing on VTK version check).

Standard_WarningsDisable.hxx/Standard_WarningsRestore.hxx pair is now used to suppress VTK warnings instead of partial disabling.
