rsx: Maintenance fixes [3]

[kd-11]

• Fix program invalidation. Avoids referencing the wrong backend shader when the current pipeline is changed for a similar one.
• vk: Avoid unnecessary dynamic state updates every draw call. Improves performance and makes debug traces easier to follow.
• gl: Fix texture slice gather/reconstruction for cubemap and 3D. Fixes broken reflections in most games when using OpenGL.

Allow host GPU label fixes flickering bushes
WCB Fixes everything
Accurate rsx reservation access + atomic fifo improves stability.
RCB, WDB, RDB not required but often improves image quality. Should work anyways in the "ideal world"

You could have been a little bit clear with your message. "This looks like fun" and two videos which are both broken and you also say "WCB fixes everything" doesn't sound like you were reporting a problem.

You're right. Refresh the pagw and videos work fine for me.
And I wasn't thinking about the communication towards another person. Especially if they weren't able to watch the videos. Still videos work perfectly for me. When I opened the website from desktop I was like what? They're mp4s what github always uses. And with 1 single refresh. Perfect.

Regardless this is now merged and I'm making sure I'm more detailed in the regression report. Uploading rsx captures to link because github can't just accept the files as is.
