[flang] Lower volatile class types (#138607)

So far, only boxes and references have had their volatile attribute set
during lowering. This patch enables the volatility of classes to be
properly represented in the ir, same as box and ref.

For simple cases, not much needs to change in the codegen or conversion
patterns because the prior work on volatile refs/boxes propagates
volatility already. I am running further testing with the strict
verification enabled to find remaining cases of incorrect/missing
volatile propagation.
