feat(renderer): add CRT shader filter with configurable effects

Browse Source 
Add CRT (Cathode Ray Tube) shader implementation as scaling filter
options (CRT EasyMode and CRT Royale) in the Window Adapting Filter
dropdown. Provides classic TV effects including scanlines, phosphor
masks, curvature distortion, gamma correction, bloom, brightness, and
alpha transparency.

- Add CRTEasyMode and CRTRoyale to ScalingFilter enum
- Implement vulkan_crt_easymode.frag shader with single-pass effects
- Integrate CRT filter into WindowAdaptPass rendering pipeline
- Add configurable CRT parameters to settings with user-friendly labels
- Add UI translations for desktop and Android platforms
- Support CRT push constants in present pipeline

The CRT filter appears alongside other scaling filters like FSR and
FSR 2.0. CRT parameter settings are only active when a CRT filter
is selected.
