Add striped 3D blitting tests

Add striped 3D blitting tests

This commit adds new tests to the color 3D image blitting group that try
to verify the proper filter (linear or nearest) is being applied in all
dimensions of the image.

Existing 3D blitting tests use source images containing gradients, with
colors values changing only small amounts from one pixel to its
neighbors. If the implementation uses the wrong filter mode (linear
instead of nearest and vice versa), a majority of these tests still
pass thanks to the test tolerance.

The new tests added by this commit use a striped pattern with slices
containing alternating red-blue colors in each of the X, Y or Z axes,
depending on the test, giving significantly different results for the
linear and nearest filter modes.

New tests:
dEQP-VK.api.copy_and_blit.core.blit_image.all_formats.color.3d.*_stripes_*

Components: Vulkan
VK-GL-CTS issue: 2672
