anv/cmd_buffer: Don't temporarily enable CCS_E within a render pass

Compressing a render target and decompressing it in the same

beneficial in some circumstances, it does not help in all. Reclaims
about 1.95% FPS for Dota 2 on some configurations.

- Enable CCS_D for input attachments
v3 (Jason Ekstrand):
- Provide performance numbers
