Adds a collection of call bytecodes which have an implicit undefined receiver argument, for cases such as global calls where we know that the receiver has to be undefined. This way we can skip an LdaUndefined, decrease bytecode register pressure, and set a more accurate ConvertReceiverMode on the interpreter and TurboFan call. As a side effect, the "normal" Call bytecode now becomes a rare case (only with calls and super property calls), so we get rid of its 0-2 argument special cases and modify CallProperty[N] to use the NotNullOrUndefined ConvertReceiverMode.
