Reverts flutter/engine#47987 Initiated by: jonahwilliams This change reverts the following previous change: Original Description: Part of https://github.com/flutter/flutter/issues/138460. In preparation for [draw order optimization](https://github.com/flutter/flutter/issues/114402) and [StC](https://github.com/flutter/flutter/issues/123671). Use a transient depth+stencil texture instead of a stencil-only texture. Doing this in isolation to detect/weed out any HAL bugs with handling the attachment.
