Fix crash when launching games without a connected controller by adding
a global NpadCondition structure at offset 0x3E200 in HID shared memory.
Games read this structure on startup to verify controller state validity,
and crash with a userspace PANIC if the data is uninitialized.
The NpadCondition structure contains:
- is_initialized flag (set to 1)
- hold_type (controller orientation)
- is_valid flag (set to 1)
These fields are properly initialized when shared memory is created,
ensuring games see valid controller state data even before any
controllers are physically connected.
Fixes crash in The Legend of Zelda: Echoes of Wisdom and other titles
that validate controller state on startup.
Based on LotP's implementation of the NpadCondition structure.

- Implement mouse wheel event handling in SDL2 backend (emu_window_sdl2)
- Add wheel event routing from GRenderWindow to input subsystem
- Add debugging logs to trace mouse wheel events through input chain
- Support mouse wheel input for mods like Ultracam when games are running (WIP)

Fix LTO linking issues on CachyOS with GCC 15.x
- Add LTO support to all core library targets (input_common, frontend_common,
network, shader_recompiler, web_service) that were missing LTO configuration
- Create citron_configure_lto() helper function for consistent LTO handling
- Implement CachyOS-specific detection via /etc/os-release and kernel version
- Apply conservative LTO flags (-flto=auto -ffat-lto-objects) only for
CachyOS + GCC 15+ to resolve linking errors with newer toolchains
- Other distributions continue using aggressive LTO settings for maximum performance
- Disable LTO on executable targets to prevent main function optimization issues
This resolves "undefined symbol" errors when building with -DCITRON_ENABLE_LTO=ON
on CachyOS while maintaining optimal LTO performance on other distributions.
Fixes linking errors including:
- Core::Frontend::EmuWindow symbols
- Core::System methods
- Settings::values
- Common logging functions
Tested on CachyOS with GCC 15.1.1 + LLD 20.1.8
