Allow `ENABLED`, `DISABLED`, `PIN_EXISTS`, and `BUTTON_EXISTS` to take multiple arguments. Also add: - Alias `ANY(...)` for `!DISABLED(...)` - Alias `ANY_PIN(...)` for `PIN_EXISTS(a) || PIN_EXISTS(b) ...` - Alias `EITHER(A,B)` for `ANY(...)` - Alias `ALL(...)` and `BOTH(A,B)` for `ENABLED(...)` - `NONE(...)` for `DISABLED(...)`
