[bug#70252] [PATCH v2 1/5] gnu: opencl-headers, opencl-clhpp and opencl-icd-loader: Replace version with %opencl-sdk-version.

[Ahmad Draidi]

These packages must be updated together. Therefore, we use a common version
variable.

* gnu/packages/opencl.scm (%opencl-sdk-version): New variable.
(opencl-headers)[version]: Replace with %opencl-sdk-version.
(opencl-clhpp)[version]: Likewise.
(opencl-icd-loader)[version]: Likewise.
