Hi all,

This series refactors the rkisp1 Filter algorithm to be fully tuning-driven,
adds rkisp1-specific control definitions for manual filter programming, and
updates imx219 tuning data accordingly.

With this series, denoise/sharpness parameters are parsed from tuning, exposed
through rkisp1 controls, and applied consistently at runtime.

Main changes:
- Parse NoiseReductionModes and Sharpness from tuning data in Filter.
- Apply tuning-derived filter parameters instead of static tables.
- Add rkisp1 vendor control definitions and control range allocation.
- Add draft NoiseReductionModeManual and manual filter control handling.
- Initialize controls from parsed tuning and support manual parameter updates.
- Add filter metadata reporting and config logging helpers.
- Add imx219 Filter tuning section, including manual mode entries.

This improves maintainability, makes sensor tuning explicit in YAML, and
provides a clear path for runtime/manual filter adjustment.

Thanks,
Rui
