More type erasure support
Summary: * `VirtualGen` gains a move-only counterpart, `VirtualGenMoveOnly` * `virtualize` added as an operator to type-erase generator names, particularly for making errors and stack traces more legible. * `FunctionRef` used to avoid heap allocations where short-lived references are sufficient.
