[Concepts] Add null check for TemplateTypeParmType::getDecl() in GetContainedInventedTypeParmVisitor
GetContainedInventedTypeParmVisitor would not account for the case where TemplateTypeParmType::getDecl() is
nullptr, causing bug #45102.
Add the nullptr check.
(cherry picked from commit 865456d589e093582acaafd17d58ad1c0cce66af)
