Do away with the flaky free_work api in the driver code which would often lose the work data in opencl and simply flush it before exiting the opencl scanhash.

Dramatically simplify the dynamic intensity calculation by oversampling many runs through the opencl kernel till we're likely well within the timer resolution on windows.

Reinstate the history on dynamic intensity mode to damp fluctuations in intensity but use an upper limit on how much the value can increase at any time to cope with rare overflows.

As we average gpu time over 5 work intervals for dynamic GPU intensity, there is no need to maintain a rolling average and it avoids the potential long term corruption of a single overflow value.
