Added a new member function to `AdvancedImageToImageMetric`, `FastEvaluateMovingImageValueAndDerivative`, which calls the multi-threaded overload of ITK's `itk::BSplineInterpolateImageFunction::EvaluateValueAndDerivativeAtContinuousIndex`, indirectly. (It does so via `EvaluateMovingImageValueAndDerivativeWithOptionalThreadId`, another new member function.) Made `AdvancedNormalizedCorrelationImageToImageMetric::ThreadedGetValueAndDerivative` faster, by calling this new `FastEvaluateMovingImageValueAndDerivative`. A large performance improvement was observed for GoogleTest unit test `itkElastixRegistrationMethod.EulerDiscRotation2D` (which uses the "AdvancedNormalizedCorrelation" metric), from ~1.5 second before this commit down to ~0.9 second after this commit, using Visual Studio 2019, Release configuration. (For a Debug configuration even from ~15 seconds before, down to ~4 seconds after this commit.)

@mstaring @stefanklein Here is the "Slower, but safer" Here is the faster overload (which has a "FIXME -- Review this "fix" and ensure it works." The performance improvement comes from skipping the memory allocation of local For the record, the "FIXME" was there already with commit InsightSoftwareConsortium/ITK@6abbc79 (6 August 2010): https://github.com/InsightSoftwareConsortium/ITK/blob/6abbc7969a90786c4c73f5d191f634db536c2d1d/Code/BasicFilters/itkBSplineInterpolateImageFunction.txx#L297 |

Replace `this->EvaluateMovingImageValueAndDerivative(...)` calls by `this->FastEvaluateMovingImageValueAndDerivative(..., threadId)` in four more metrics: itkAdvancedKappaStatisticImageToImageMetric itkParzenWindowMutualInformationImageToImageMetric itkAdvancedMeanSquaresImageToImageMetric itkPCAMetric_F_multithreaded Follow-up to pull request #556 commit c8c4a6a "PERF: Make AdvancedNormalizedCorrelationImageToImageMetric faster"

Replace `this->EvaluateMovingImageValueAndDerivative(...)` calls by `this->FastEvaluateMovingImageValueAndDerivative(..., threadId)` in the "Threaded" member functions of six more metrics:
itkAdvancedKappaStatisticImageToImageMetric
itkAdvancedMeanSquaresImageToImageMetric
itkParzenWindowHistogramImageToImageMetric
itkParzenWindowMutualInformationImageToImageMetric
itkPCAMetric_F_multithreaded
itkSumSquaredTissueVolumeDifferenceImageToImageMetric
Expected a significant performance gain on the run-time duration.
