Aurelien Delval 5e3231e7e3 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.
