Combine visibility queries in check_visibility_system (bevyengine#10196)

# Objective

Alternative to bevyengine#7310

## Solution

Implemented the suggestion from
bevyengine#7310 (comment)

I am guessing that these were originally split as an optimization, but I
am not sure since I believe the original author of the code is the one
speculating about combining them up there.

## Benchmarks

I ran three benchmarks to compare main, this PR, and the approach from
bevyengine#7310
([updated](https://github.com/rparrett/bevy/commits/rebased-parallel-check-visibility)
to the same commit on main).

This seems to perform slightly better than main in scenarios where most
entities have AABBs, and a bit worse when they don't (`many_lights`).
That seems to make sense to me.

Either way, the difference is ~-20 microseconds in the more common
scenarios or ~+100 microseconds in the less common scenario. I would
speculate that this might perform **very slightly** worse in
single-threaded scenarios.

Benches were run in release mode for 2000 frames while capturing a trace
with tracy.

| many_lights | 7310 | 842.5 |

## Notes

Technically this behaves slightly differently -- prior to this PR, view
visibility was determined even for entities without `GlobalTransform`. I
don't think this has any practical impact though.

IMO, I don't think we need to do this. But I opened a PR because it
seemed like the handiest way to share the code / benchmarks.

## TODO

I have done some rudimentary testing with the examples above, but I can
do some screenshot diffing if it seems like we want to do this.
