Allow references to uninitialized ambient properties (#36112) 
Previously these were incorrectly treated just like normal properties:

```ts
class Parent {
    a: any;
    constructor(arg: any) {
        this.a = arg;
    }
}
class Child extends Parent {
    declare a: number;
    constructor(arg: number) {
        super(arg);
        console.log(this.a);  // Property 'a' is used before being assigned. (2565)
    }
}
```

Get jsdoc host from chained assignment (#36111) 
* Get jsdoc host from chained assignment

getSourceOfAssignment previously only checked one level of binary
expression instead of following binary expressions all the way to the
right. This meant that binding of `@constructor` would fail in the
following example:

```js
/** @constructor */
a = b = function () { }
```

* cleanup lint

* use existing utility

Fix crash in codefixes re: braces of class body (#36087)

Previously, the code that finds braces of a class body assumed they were
always there. This is not always the case, so this code checks for
that.

Report time spent in updateGraph (#35675) 
Add a response property indicating how much of the elapsed time (from
`onMessage` to `doOutput`) was spent in `updateGraph` calls.  If there's
no `updateGraph` call, the property is undefined, to save space (with
the downside that it's harder to tell whether a given telemetry event
could have had the property).

Fixes #34774
