TVM has upgraded to use C++17 for compilation (apache/tvm#12337), and the codebase is no longer compatible with C++11 anymore due to the use of std::string_view (apache/tvm@d2f9f25).

Accordingly, RAF is upgraded to use C++17 since this PR. However, the nvcc compilation with c++17 raised the following error:

raf/include/raf/././ir_ext.h:71:33: error: 'may_sharetvm' has not been declared
  mutable Var may_share{Var()};

The include chain is *.cu -> kernel_utils.chu -> device.h -> ir.h -> ir_ext.h. I removed the dependency from ir.h to ir_ext.h to let *.cu files not include ir_ext.h and the problem is solved, although I still don't know the root cause. Meanwhile, with this change, #include "raf/ir.h" no longer includes ir_ext.h and dataflow_pattern.h implicitly, so I changed header files to directly include them if needed.
