Implement computation of tmp_c and dtmp_c in OpenACC

These 2 kernels seem to give good speedup compared to the CPU BLAS
versions. However, the current GPU implementation of factor_een_deriv seems to
be slightly slower (on the tested machine).

TODO Start modifying dedicated function to implement offloading
Also, as of now, Fortran preprocessor flags should be passed manually,
we need to manage this in the configure.ac in the future. For now, when
using gfortran, you should pass FCFLAGS="-cpp -DWITH_OPENMP_OFFLOAD" to
enable offloading.

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.
