vulkan-demos: Add recipe

Sascha Willems collection of Vulkan demos is useful as a smoke testing
tool.

* Add patch to install binaries and data.
* Add patch to fix build on X86
* Use a combination of patch and do_install_append to avoid some 3D
models with unclear licensing.

+Subject: [PATCH] Support installing demos, support out-of-tree builds
+
+This is especially useful for cross-compile situation where testing
+happens on target.
+
+-DRESOURCE_INSTALL_DIR=<path> decides where data is installed (and
+where the binaries will load the data from): if it's left empty,
+then nothing will be installed and binaries will load the data from
+CMAKE_SOURCE_DIR.
+
+Binaries are now correctly built in CMAKE_BINARY_DIR.
