Vulkan MSAA: Compatibility problems

• Star Ocean characters not visible on 2D screens on NVIDIA. Very likely stencil buffer related. See Remove D3D9 support, to make future changes easier #19951 (comment)
• @Kiyuja reports: Sprite issues when using MSAA on ModNation Racers, part of the UI got yellow stretched stripes, making it look like a cartoony sun, even tho its supposed to be a clean blue circle. Needs repro and framedump, ideally - can't figure this one out.

Do add more if you know any.

#20233 fixes the Star Ocean issue.

Moving the rest to 1.20.

@FATCatAndroid12 As the PSP relies a lot on preserving depth and stencil data between passes, it needs to expose the VK extension VK_KHR_depth_stencil_resolve for us to be able to use MSAA.

@hrydgard thanks for answering my question
yeah my Nova 3i doesn't have that vk extension 😅

While my Redmi Note 9 does have.
