Fixes flutter/flutter#131610

Since we're not blocking on presentation, we can have multiple images pending. This is generally good, but for the backpressure from acquireNextImageKHR to be valid it needs to have a finite timeout.

Pick a somewhat arbitrary but fairly long ms duration. See also: flutter/flutter#131698

It looks like this pull request may not have tests. Please make sure to add tests before merging. If you need an exemption to this rule, contact Hixie on the #hackers channel in Chat (don't just cc him here, he won't see it! He's on Discord!).

If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix?

Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing.

I was about to say, "if this is a magic number anyway, let's make it the same as the Metal backend.". The docs for [CAMetalLayer nextDrawable] say "If all drawables are in use, the layer waits up to one second for one to become available, after which it returns nil.". If this was intentional, amazing attention to detail!
