vkcube: Fix disturbed rotation after many iterations
vkcube computes the model matrix for the cube by repeatedly multiplying
a rotation matrix with it. After a sufficient number of iterations the
matrix becomes disturbed (likely due to numerical errors) and stops
being orthogonal and the cube vertices start scaling increasingly on the
XY plane.
* Orthonormalize the model matrix after each multiplication to prevent
the scaling.
* Use mat4x4_rotate_Y() instead of mat4x4_rotate() as it is less
verbose.
* Remove unused duplicate vkcube_vs_uniform struct.
