Subject: [PATCH] [api-minor] Remove the unused `convertToViewportRectangle`
 method in the `PageViewport` class

This method has been completely unused for many years, possibly as far back as PR 8030, hence we can avoid shipping a little bit of dead code.

*Note:* If there's any third-party code depending on it, updating it ought to be as simple as changing
```javascript
const r = viewport.convertToViewportRectangle(rect);
```
into
```javascript
const r = [
  ...viewport.convertToViewportPoint(rect[0], rect[1]),
  ...viewport.convertToViewportPoint(rect[2], rect[3])
];
```
