task intents for records and/or record fields

Feature request. As a Chapel programmer, I've had situations where I wanted t…o put a `forall` loop inside a method for a record type `R` and update some record fields within the body of that `forall` loop. To do that, you would need to provide a **task intent for each record field**, but this does not work today. This may also get tricky depending on the default intent or user-specified intent (#13319) of the record. The documentation for ["Forall Loops"](https://chapel-lang.org/docs/1.25/primers/forallLoops.html#task-intents-inside-record-methods) also indicate this limitation: > At present, the record fields, as well as the method receiver `this`, are always passed by default intent and cannot be listed in a with-clause.
