this PR fixes #91835. For `DeclRefExpr` in lambda's function body, it will references to original variable declaration in AST rather than `FieldDecl` for lambda class, so it's needed to find the corresponding `FieldDecl` and bind `DeclRefExpr`'s value to it. This is already implemented for variables that are not in a structured binding structure, so I extracted that part of the code so that it can be used in the structured binding case.
