This is the major change - move the low level appending to the ValueBuffer itself
Then all the recursion seems to fall into place

This PR targets the following from @friendlymatthew
VariantBuilderapache/arrow-rs#7914The high level idea is to handle the low level recursion in
ValueBufferin a uniform wayThen the higher level VariantBuilders simply call into that
I ran out of time today, but I think this approach is pretty promising
