Add a section warning about possible issues with bundling the
Khronos loader with an application/engine.
Also, rename "desktop loader" to "Khronos loader" since it is now
used for more than the original desktop targets.
Add a section in the application documentation on how to debug possible
layer issues.
Also add a small note on why a layer may need to intercept pre-instance
functions.
Feedback from Khronos was that "Implementation" was for the entire
set of Vulkan components underlying the application (including the
loader, layers, and drivers). Instead, what I had been calling
implementation should be called "Driver" including software
implementations of Vulkan at that level.
Also update the LOADER_DEBUG option "implem" to take "driver" as well.
All images also updated.
Update the loader documentation in the following ways:
1. Move documentation to new "docs" folder"
2. Split LoaderAndLayerInterface.md into multiple docs to focus
on target audience:
- Top-Level LoaderInterfaceArchitecture.md
- Applications LoaderApplicationInterface.md
- Layers LoaderLayerInterface.md
- ICDs LoaderImplementationInterface.md
3. Upload newer images and their corresponding original Inkscape files.
4. Cleanup and update sections on Linux directory search
5. Add new sections to detail items missing
- VkConfig
- Handling undef Fuchsia
6. Language cleanup
Thanks to @charles-lunarg and @smcv for feedback and various section language
corrections.
