LibJS/Bytecode: Add Operand in/out to all the bytecode codegen helpers
This is pure prep work for refactoring the bytecode to use more operands instead of only registers. generate_bytecode() virtuals now return an Optional<Operand>, and the idea is to return an Operand referring to the value produced by this AST node. They also take an Optional<Operand> "preferred_dst" input. This is intended to communicate the caller's preference for an output operand, if any. This will be used to elide temporaries when we can store the result directly in a local, for example.
