DataFormatsTRD: place the Tracklet64 bit masks in the constant address space

MSL requires every variable at program scope, class-scope statics included, to
name an address space. GPUglobalconstexpr() expands to constexpr everywhere
except Metal, so this is a no-op for host, CUDA, HIP, OpenCL and cling.

These were missed by the earlier pass: the header they sit in only started
being compiled once the errors ahead of it were gone.
