Use vk::StructureChain on pipeline creation.

[asuessenbach]

In chapter 12 and following, a structure chain is manually created on creating the pipeline.

Should we change that to using a vk::StructureChain, instead?

This improves readability by a lot!

So yes, I'm for doing it like this in all subsequent chapters.

Especially have a look at chapters 32 and 33, which need some special handling on the vk::StructureChain.

Note that some chapters have errors both with and without this PR:

• 18, 22: validation layer errors, nothing is displayed
• 26, 38: validation layer warnings
• 35, 36: does not find some ktx.dll, exits

The issues with 35, 36 are prob. related to vcpkg. They work fine for me, but getting those to work on Windows was quite a hassle :/

Last time I checked pretty much all chapters had validation errors, we need to tackle these, see #134
