Add a flag to the OpenCLZone indicating whether we are performing the
first-start OpenCL functionality verification, so that if we run into
a crash that is caught by the VCL VCLExceptionSignal_impl() handler,
we terminate the process with the EXITHELPER_NORMAL_RESTART
status after first having disabled OpenCL use. The wrapper process will
then restart soffice.bin. This is for Windows only so far.
This matches what we do if OpenGL fails early during start of
LibreOffice.

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.

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.
