scoped_range does not work with domain::global about nvtx

[zygfrydw]

I have done some experiments with NVTX source code and the following changes seams to fix the issue:

I have changed

// NVTX/include/nvtx3/nvtx3.hpp line 940
template <>
inline domain const& domain::get<domain::global>() noexcept
{
  static domain const d{};
  return d;
}

to:

template <>
inline domain const& domain::get<domain::global>() noexcept
{
  static domain const d{"global"};
  return d;
}

Can you verify if the modification makes sense to other NVIDIA tools?
