With the new XkbConfig struct, it is now easier to just use xkbcommon's
default configuration, by moving the xkbcommon specific options into a
struct with according documentation.
Additionally, anvil now uses xkbcommon's defaults with all backends
(previously, the winit backend had a hardcoded french keyboard layout).
