createTexture validation tests.

> - {any dimension, mipLevelCount} = 0
>     - x= every texture format
> - sampleCount = {0, 1, 4, 8, 16, 256} with format/dimension that supports multisample
>     - x= every texture format
> - sampleCount = {1, 4}
>     - with format that supports multisample, with all possible dimensions
>     - with dimension that support multisample, with all possible formats
>     - with format-dimension that support multisample, with {mipLevelCount, array layer count} = {1, 2}
> - 1d, {width, height, depth} > whatever the max is
>     - height max is 1 (unless 1d-array is added)
>     - depth max is 1
>     - x= every texture format
> - 2d, {width, height, depth} > whatever the max is
>     - depth (array layers) max differs from width/height
