  xkbcomp: Drop trailing NoSymbol and NoAction()
  
  This brings us closer to what `xkbcomp` outputs. One should use
  the explicit `VoidSymbol` instead of `NoSymbol`, in order to avoid
  dropping empty levels.
  
  This may affect keys that rely on an *implicit* key type. Example:
  
  - Input:
    ```c
    key <> { [a, A, NoSymbol] };
    ```
  - Compilation with xkbcommon \< 1.9.0:
    ```c
    key <> {
      type= "FOUR_LEVEL_SEMIALPHABETIC",
      [a, A, NoSymbol, NoSymbol]
    };
    ```
  
  - Compilation with xkbcommon ≥ 1.9.0:
    ```c
    key <> {
      type= "ALPHABETIC",
      [a, A]
    };
    ```

• Trailing `NoSymbol` and `NoAction()` are now dropped. This may affect
  keys that rely on an *implicit* key type.
  
  Example:
  - Input:
    ```c
    key <> { [a, A, NoSymbol] };
    ```
  - Compilation with xkbcommon \< 1.9.0:
    ```c
    key <> {
      type= "FOUR_LEVEL_SEMIALPHABETIC",
      [a, A, NoSymbol, NoSymbol]
    };
    ```
  
  - Compilation with xkbcommon ≥ 1.9.0:
    ```c
    key <> {
      type= "ALPHABETIC",
      [a, A]
    };
    ```
