feat: add support for DualSense Controller(USB) on Windows

[ShadyLeaf]

This PR adds a small Windows-only USB DualSense input backend.

The backend reads DualSense USB HID input reports through Win32 HID APIs and maps them into the existing gamepad-changed event names used by the current gamepad model. It does not change the frontend.

Scope:

• USB DualSense only
• Windows only
• no Bluetooth support
• falls back to gilrs when no USB DualSense is available
• keeps the existing gilrs path for Xbox/XInput and non-Windows platforms

Notes:

• When a USB DualSense is connected on Windows, it is preferred over the gilrs backend.
• Bluetooth DualSense devices are ignored by this backend and continue through fallback behavior where supported by gilrs.
