[Task] rsx: Fix surface cache references

[kd-11]

During the investigation into the odd crash observed in Resistance FOM, it became clear that we're holding on to raw pointers from the surface cache. That's just lazy and dangerous, C++ has the tools for safer memory management.

Is that task related to the remaining issue ending with a DEVICE_LOST? As far as I see, PR #16836 fixed the issue #14809 (another bug on surface cache)

Yes, at least partially.

This will need some planning, I might as well refactor the texture cache while doing this.

good thanks. I will test the PR when it will be available
