* Skip neighbor list for very small systems

* Fixed typos

* Don't skip box size check when not using neighbor list

* Made test larger to ensure it uses neighbor list

It may contain a garbage value, and if it is large then
updateNeighborListSize does not force reorder atoms after 25 steps
in extremal cases.

* Use 768 instead of 384 threads in generic kernels

* Use 1536 instead of 1024 threads in force kernels.

- Appear to be copy and pasted from getPositions and were not removed

* Flushing optimization

* Remove unnecessary checks

* Profiling of OpenCL kernels

* Minor improvements to profiling

* Use VkFFT for OpenCL

* Updated comments for OpenCLFFT3D

This initialization is needed to prevent segfault during object destruction in certain circumstances (e.g., when a `Force` is changed before calling `Context.reinitialize()` and this change causes the corresponding `ForceImpl` to throw an exception).

Without this fix, we see cases in which not all work-items in a thread group end up hitting the same number of barriers, which leads to a hang in OpenCL GPU execution.

It allows to use a faster float-to-int64 in the HIP platform.

* DrudeLangevinIntegrator has getSystemTemperature()
