Some devices can manage global values to push and pull different values.
In the CUDA runtime, this is covered by cudaMemcpyToSymbol/cudaMemcpyFromSymbol functions.
But other APIs may offer similar functionalities.
This proposal add the possibilities to manage such global values via a new class and new sycl::handler member functions.
The proposal is still a bit incomplete as regular C++ global variable can potentially be handled by the sycl::handler extension
without requiring the new 'sycl::symbol' class. but limitation have yet to be explored.
