Z: Enable 2D array inlining with non-zero constant second dimension

Previously, inlining of constant 2D arrays with a non-zero second
dimension was disabled on z due to limitations in handling such cases.
However, recent improvements have resolved those issues, making it safe
and beneficial to inline these arrays.
Remove the constraint that prevented inlining of non-zero constant
second dimension 2D arrays.
