RSDK-11726 — Deprecate GetImage and Format in Go SDK/RDK

[hexbabe]

This PR deprecates RenderFrame and GetImage (logging deprecation warning) in camera/client.go and camera/server.go, deprecates format (fully removed), and replaces all usages throughout RDK. It also deletes GetImage from unit testing.

Manual Tests

linux/arm64

• Test with config with multiple camera resources
• Test rtsp with and without passthrough
• Test ReadImage and GetImages collectors
• Test CPU usage is on par with prev viam-servers
• Test warning logs when GetImage is called
