General LSRKStep cleanup, including always using (tcur,ycur) as the current stage solution, and to only call RHS on that vector.

This is the third in a sequence of PRs for ARKODE to support our FES collaborators. Please review this one after #814. When the stack is complete, we'll do a final PR into develop

This PR should be ready to review -- all CI issues resulting from the new release have been resolved.

Other than a side effect of removing the yn to ycur copy in #813, this looks good to go


The variables (ark_mem->tcur, ark_mem->ycur) should
contain the current time and solution at each stage within
the time step.

Removing the copy in #813 to update ycur with yn will require some updates below to revert ycur back to yn (looks like just the first RHS call at the start of a step)
