Validation Warnings on Device Creation

[CyclotomicDev]

Recently switched from Windows to Manjaro (Linux), and all my projects using this crate now give the following validation warnings from a call to Instance::create_device:

This is the case for the tutorial code ,"04_logical_device.rs", but not for the corresponding C++ tutorial code.

Well, this is awkward, it breaks my entire method for organizing extensions.

I didn't realize that there are functions like these that are defined in device-level extensions but are expected to be loaded from the instance rather than the device.

I'll need to think about how to handle functions/extensions like these.

I've fixed the immediate issue (loading these commands with the device loader function instead of the instance loader function).

I opened #286 to look into allowing users to easily call these commands with only an instance (if the commands are available).
