vulkan: Flickering/Corrupt/Swapped Textures on Intel drivers

[retroNUC]

Summary

Textures in the game appear to be flickering/corrupt/swapped when being encountered for the first time on Vulkan. Most obvious on the title screens. Default settings, only just started using RPCS3. Game rendering fine when using OpenGL.

Lol, the classic event sync bug on AMD proprietary. Needs KHR_synchronization2 but we also have an in-place workaround for AMD that should resolve this one as well.

Should be fixed by #12072. Please verify as I do not have the required hardware.

Tested on 0.0.22-13643 with included change. While the majority of texture corruption appears to be gone with this fix, especially with flickering on moving/animated sprites, some texture corruption and disappearing sprites still remain on Vulkan that do not occur on OpenGL.

Reopening.
Needs synchronization2 extensions to fix it properly.

[kd-11]

Should be fixed by #14065 assuming no driver bugs on intel.

[retroNUC]

Unfortunately, issue is still occurring in latest nightly RPCS3 build (0.0.28-15229), with latest Intel drivers (101.4502). New logs/capture attached.
