desktop: validate OpenCL drivers before use.
OpenCL validation needs to happen before drivers are used in
anger. This should isolate any crashes, and/or mis-behavior to
We use app version, CL driver version and file time-stamp to
trigger re-testing the device. If anything fails: hard disable
OpenCL.

We use an opencl validation sheet (cl-test.ods) and install it.
It is a minimal CL set - it requires a very short formula group
length, and combines several CL functions into few formulae to
test more.

The sheet structure, in particular the manual squaring / SQRT is
necessary to stick within the default CL subset, and ensure that
formulae are CL enabled from the root of the dependency tree up.

Memory usage is in normal range in newer version when disabling OpenCL (or
using with OpenCL prior to the given commit )
