cube: Check in SPIRV code
The shader code used by vkcube & vkcubepp is now checked into the source.
This prevents users from needing a version of glslang on the system in
order to build the project. While the existing mechanism of fetching a
glslang binary from github was adequate, the version used linked to
VS 2013 which caused build failures with rather cryptic linker errors.
Since changing the shaders happens very infrequently, the decision has
been made to check in the spir-v code.
The CMake logic to compile the shaders remainds, but is put behind a
new build flag COMPILE_CUBE_SHADERS.

-#### glslang
-
-This repository has a required dependency on the `glslangValidator` (shader
-compiler) for compiling the shader programs for the vkcube demos.
-
-The CMake code in this repository downloads release binaries of glslang if a
-build glslang repository is not provided. The glslangValidator is obtained
-from this set of release binaries.
-
-If you don't wish the CMake code to download these binaries, then you must
-clone the [glslang repository](https://github.com/KhronosGroup/glslang) and
-build its `install` target. Follow the build instructions in the glslang
-[README.md](https://github.com/KhronosGroup/glslang/blob/main/README.md)
-file. Ensure that the `update_glslang_sources.py` script has been run as part
-of building glslang. You must also take note of the glslang install directory
-and pass it on the CMake command line for building this repository, as
-described below.
-
-Note that this dependency can be ignored if not building the vkcube demo
-(CMake option: `-DBUILD_CUBE=OFF`).
