Removed ISPC runtime dependency and level zero loader requirement
Add DEPENDENTLOADFLAG linker parameter for Windows binaries, restricting DLL loading behavior
Superbuild updates to latest versions of dependencies

This Open VKL release adds support for Intel® Arc™ GPUs, Intel® Data Center
GPU Flex Series and Intel® Data Center GPU Max Series through SYCL.
- The SYCL support of Open VKL is in beta phase. Current functionality,
  quality, and GPU performance may not reflect that of the final product.
- Open VKL CPU support in this release remains at Gold level,
  incorporating the same quality and performance as previous releases.
API changes:
- Handle types are now passed by pointer in the following APIs:
  - vklComputeSample*()
  - vklComputeGradient*()
  - vklGet*IteratorSize*()
  - vklInit*Iterator*()
  - vklIterate*()
- vklLoadModule() has been removed; compile-time linkage to an Open VKL
  device implementation (cpu or gpu) is now required
- Added vklInit() API, which must be called to initialize the library
- VKL_FILTER_[TRILINEAR,TRICUBIC] are renamed to
  VKL_FILTER_[LINEAR,CUBIC]
- VKLAMRMethod enum is now uint32_t
- structuredSpherical volumes: the gridSpacing default now results in
  the volume occupying a full sphere
Added new examples demonstrating GPU usage: vklExamplesGPU and
vklTutorialGPU
Superbuild updates to latest versions of dependencies

- Introducing interval and hit iterator contexts, which hold iterator-specific configuration (eliminates value selector objects)
- Interval and hit iteration is now supported on any volume attribute
- Interval iterators now include a time parameter
- Interval iterators now support the intervalResolutionHint parameter, replacing maxIteratorDepth and elementaryCellIteration
Supporting configurable background values; default is now VKL_BACKGROUND_UNDEFINED (NaN) for all volume types

Structured regular volumes:
- Added support for tricubic filtering
- More accurate gradient computations respecting filter mode
- Hit iteration robustness improvements
VDB volumes:
