Subject: [PATCH] Allow Cython-3 and resolve compilation errors

cupy/_core/_kernel.pyx:1159:24: '__module__' redeclared
Fixed by removing "readonly object __module__"

cupy/_core/dlpack.pyx:152:25: Cannot assign type 'void (DLManagedTensor *) except * nogil' to 'void (*)(DLManagedTensor *) noexcept'. Exception values are incompatible. Suggest adding 'noexcept' to the type of 'deleter'.
cupy/_core/dlpack.pyx:154:57: Cannot assign type 'void (object) except *' to 'PyCapsule_Destructor' (alias of 'void (*)(object) noexcept'). Exception values are incompatible. Suggest adding 'noexcept' to the type of 'pycapsule_deleter'.
Fixed by adding noexcept to those functions

Closes: https://github.com/cupy/cupy/issues/4610
