radv: Merge dEQP default skips into all generation-specific skip lists

https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/8147
obsoleted
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/4656 so the
default skips are not being used.

Instead, merge the defaults into each generation's skip list. Also
remove the "Fixed by CTS 3dddaeca8 ("Fix source blit image size")",
since the VK-GL-CTS has been updated to vulkan-cts-1.2.6.0 already,
which includes 3dddaeca8

Nowadays, the only option is to have default skips per GPU
version (c.f. GPU_VERSION variable in deqp-runner), since the runner
doesn't have a "skip list merge" feature.

v2.
  - Removed deqp-radv-polaris10-skips.txt in response to Samuel's feedback.

v3.
  - Add review tags.
