Fixes for sparse texture clamp tests.

When initializing the test texture, bind to an image unit, setting the
layered parameter to GL_TRUE instead of GL_FALSE. For array textures,
the compute shader used indexes all layers of the textures. For
non-array textures, the parameter has no effect.

For cube map array textures, copy vertex array data to a higher-scoped
memory location, such that the draw call is not invoked with a dangling
pointer.

Swap the Z and W coordinates of the texture size calculated by shaders,
such that Z is the number of cube faces, and W is the number of layers
(which is how the coordinates were otherwise already being used).

Set up texture coordinates for KHR-GL46.sparse_texture_clamp_tests.*
such that the fragment shader correctly computes layer and face indices,
given the corrected texture size and existing shader generation logic.
