Computes the gauge-transformed Tags::EvolutionGaugeBoundaryValue<Tag>
for any of the boundary tags needed in the evolution.
Most of these computations involve first interpolating via a Spectral::Swsh::SwshInterpolator
to the new angular grid, followed by manipulations associated with the tensor transformation of the metric and its derivatives. Individual template specializations contain detailed explanations about the respective gauge transformations.
