[Task] Optionally simulate depth test for Z-prepass algorithms #13078

Mostly a problem with games that make use of Z-prepass. We can never truly guarantee invariance without using the shader interpreter. Some games have completely different vertex shader setups for both passes and this causes some flickering/Z-fighting when the color pass happens with EQUAL comparison.

Games I test which seems to have a Z-fighting issue: Call of Duty: Black Ops (#13727) https://youtu.be/m9O5LPwYDhA?t=669 Madden NFL 25 (Helmets) Battleship (Water) Watchmen: The End is Nigh Part 2 #13762 The Darkness #13761 Blazing Angels 2: Secret Missions of WWII #13354
