XKB configuration is ignored

## Bevy version

`bevy = { version = "0.15.2", features = ["dynamic_linking", "wayland"] }`

## \[Optional\] Relevant system information

Arch Linux 6.12.10-zen1-1-zen. Wayland Sway WM.

## What you did

I'm using xkb_file sway command to modify default keyboard layout, it includes swapping Ctrl with Caps Lock keys functionality. Every other application, games, steam games, wine and etc uses my overridden configuration. But bevy does not. So to be clear

| Physical key | Key functionality |
|--------------|-------------------|
| Ctrl | Caps Lock |
| Caps Lock | Ctrl |

xkb file: https://github.com/SL-RU/i3config/blob/think/default.xkb

command to reproduce: `swaymsg input '*' xkb_file ./default.xkb`

## What went wrong

When I press physical key CapsLock `ButtonInput` receives press `KeyCode::CapsLock` and when I press physical key Ctrl `ButtonInput receives `KeyCode::Ctrl`. So it is ignoring system setting and seems to be using some default xkb configuration

Reproduce the issue on Arch Linux with Wayland and Sway using the linked default.xkb file and `swaymsg input '*' xkb_file ./default.xkb`. Trace Bevy's keyboard input handling and compare its reported KeyCode values with the system remapping. Done means the swapped Ctrl and Caps Lock keys produce the corresponding remapped input in Bevy.
