BeanInfoDigger cannot handle FlexibleTypes

[HarrisL2]

Issue summarized from a run of the Scala Open Community Build

When compiling this project with -Yexplicit-nulls enabled, the project fails with the following message:

java.lang.RuntimeException: Unspported type :FlexibleType(OrType(TypeRef(TermRef(ThisType(TypeRef(NoPrefix,module class java)),object lang),class String),TypeRef(ThisType(TypeRef(NoPrefix,module class scala)),class Null)),TypeRef(TermRef(ThisType(TypeRef(NoPrefix,module class java)),object lang),class String))

The cause is from

commons/src/main/scala/org/beangle/commons/lang/reflect/BeanInfoDigger.scala

Lines 198 to 211 in 76013a8

	def resolveType(typeRepr: TypeRepr, params: Map[String, TypeRepr]): Expr[AnyRef] = {
	var tpe = typeRepr
	var args: List[Expr[AnyRef]] = List.empty
	tpe match {
	case d: TypeRef => if (tpe.typeSymbol.flags.is(Flags.Param) && params.contains(tpe.typeSymbol.name)) tpe = params(tpe.typeSymbol.name)
	case c: AppliedType => args = resolveParamTypes(c, params)
	case d: AnnotatedType => tpe = d.underlying
	case c: ConstantType =>
	case n: OrType =>
	case _ => throw new RuntimeException("Unspported type :" + tpe)
	}
	if args.isEmpty then typeOf(tpe)
	else '{ Array(${ typeOf(tpe) }, Array(${ Varargs(args) }: _*)) }
	}

where FlexibleTypes are not handled.

The fix is to add a corresponding case to the match and recurse on the underlying type. This might require a minor refactor.
