Add selection mechanism for offload mode in Jastrow
This system adds an additional field to the QMCkl context to store the offload mode currently in use for each kernel (in this commit, this has been implemented for Jastrow as an example). This will be useful to test different offloading versions that can be easily toggled on/off at compilation and at runtime.
