Vulkan: Fix incompatible redefinition of cube faces

The TextureVk::mRedefinedLevels bitmask tracked which levels are
incompatibly redefined, greatly reducing the complexity of dealing with
GL's mutable textures.

It did not however take into account the fact that GL allows each
cubemap face to be separately redefined (unlike 2D arrays, where all
layers are defined together).  This change turns the bitmask into an
array of bitmasks.  Previously, a single bit represented whether the
level is incompatibly redefined.  Now, elements of the array track the
same information for each cube face.  For non-cube-map textures, only
element 0 is used.
