Test OpArrayLength with stride larger than element size

Test OpArrayLength with stride larger than element size

This new test is similar to
dEQP-GLES31.functional.compute.basic.write_multiple_unsized_arr_*
but an array stride is changed. This verifies that OpArrayLength
implementation calculates the array size correctly even
when an array element size and a stride don't match.
