We should also add a parser test with "createParenthesizedExpressions": true

@babel/generatorgenerates incorrect code@this[bar]from@(this[bar])In this PR we ensure that
@babel/generatorgenerates correct codes for non-simple decorator expressions such as@(this.foo().bar). In the first commit we mark all these non-simple expressions as "parenthesized", so that we generate correct AST for cases like@(this).bar. The second commit fixes the generator issue.The current decorator spec ("2022-03") share the same decorator expression grammar production with "2021-12" and "2018-09".
