feat: remove frame generation options from all platforms

Frame generation was marked as WIP and not ready for production use.
This commit removes all frame generation related code and UI elements
to prevent users from enabling an incomplete feature.

Changes:
- Remove frame generation settings from Android UI (Kotlin/XML)
- Remove frame generation settings from Desktop UI (Qt/C++)
- Remove frame generation enums and settings from core (C++)
- Remove frame generation Vulkan renderer implementation
- Remove frame generation shader files
- Update CMake build configuration
