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.
