OpenCL stubs

Afaik DAZ uses its own "opencl loader .dll" in the DAZ installed folder, and
even tho DAZ sais it only requires OpenCL 1.2, it might load system opencl.dll
checking for export symbols > 1.2, and fail if it is not found.

The reason for concluding this is that after reverting ref. to bug #52389, i
added stubs to wine's opencl.spec file up-to what i found when comparing with
Win10 OpenCL Platform 3.0 (/windows/system32/opencl.dll), and my device was
then detected and used in DAZ.

I will test this further once bug #52389 is resolved (i have seen the PR
posted, and if its not upstreamed by the time i get home, i will test that).

Does it sound too far-fetched that DAZ's loader somehow loads symbols from the
system opencl.dll and only pass this if certain symbol is found? The opencl.dll
in windows system folders are from Khronos, and i think i read someplace that
this gets updated by Windows update automatically regardless of drivers
installed as this is kind of the "OpenCL ICD loader" for windows.
