refactor(transformer): shared `VarDeclarations` (#6170) First step towards #5049. Various transforms need to add a `var` statement at top of enclosing statement block. e.g.: ```js // Input a ??= b; ``` ```js // Output var _a; (_a = a) !== null && _a !== void 0 ? _a : (a = b); ``` Each of these transforms previously maintained it's own stack and added `var` statements individually. Share this functionality in a "common" utility transform which maintains a single stack to serve them all.
