Moved the creation and resizing of the v and w high modes from the A2A class to the A2A module and made them an output of the module. This means that they have to be inputs of the contration modules and they will freed from memory if they are no longer needed.

Test for faster implementation of meson field inner loop
...
This should be possible to cache block at outer levels, global sum across nodes not performed
and deferred to caller to block them all into a big all reduce.
Nc=3 and Fermion is hard coded in an ugly way. We might think about benchmarking whether
a product without the conjugate should be made available by Grid.
It is not clear whether the explicit unroll, or the performing of conjugate on left once
was the real source of the speed up.
Gives 70-80 GF/s on my laptop (single) half that double, and 70GB/s to cache.
This is competitive with dslash and a reasonable stopping point for the optimisation. If necessary we can revisit.
