opencl: OpenCLZone, detect CL device change and disable CL on crash
Guard OpenCL calls with OpenCLZone, so if a OpenCL call crashes we
detect this and disable OpenCL so next time the user doesn't encounter
the crash at the same calculation because he has a broken OpenCL
drivers. Similar has been implemented for OpenGL with good results.
Additionaly we persistently remember a known good OpenCL device ID and
driver version so we can match this and perform calculation tests when
they change. This is to ensure that the selected OpenCL device performs
as we expect. In this commit the calculation tests aren't included yet.
Remove complex static initializer in opencl wrapper library.
