rewrite-scala: add public canonical constructors to S.TuplePattern and S.FunctionCall (#7462)

Both classes previously exposed only a private `@AllArgsConstructor`-generated
canonical constructor whose first parameter is the padding `WeakReference`.
Deserializers (such as moderne-ast-write's V3 codegen) skip non-public
constructors and constructors that take a `WeakReference`, so these types
were invisible to static codegen and fell through to the dynamic-schema
read path — where, lacking any other public constructor, construction
failed and source files were substituted with a `Quark` + `DeserializationError`
marker.

Adding `@RequiredArgsConstructor` generates a public canonical constructor
that excludes the `@NonFinal` padding field, matching the pattern already
used by `S.CompilationUnit` and by rewrite-java types such as `J.MethodInvocation`.
The private padding-aware constructor remains for internal use.
