Cache the viewport to make invalidation faster (#6918) 
In `Renderer::TriggerRedraw`, the act of fetching the viewport from the
`pData` over and over is wasted time. We already have a cached variable
of the viewport that is updated on every scroll check (on
`TriggerScroll` and on `PaintFrame`.) Scrolling wouldn't be working
correctly if the clients weren't already notifying us that the viewport
has changed for scroll purposes, so we can just keep using that cached
value for the invalidation restriction to speed things up over fetching
it again.

## Validation Steps Performed
- Run `time cat big.txt`. Checked average time before/after, WPR traces
  before/after.
