refactor(cmake): simplify ImGui test engine integration and feature flags

- Updated CMake configuration to always include the ImGui Test Engine when tests are enabled, removing conditional checks for UI tests.
- Simplified feature flag management by enabling JSON and gRPC by default, with a minimal build option to disable only the most expensive features.
- Enhanced status messages to provide clearer feedback on build configurations and feature availability.

Benefits:
- Streamlined integration of the ImGui Test Engine for testing purposes.
- Improved clarity in feature flag settings, making it easier to manage build configurations.
