[Bug] Compilation error in GPU aggregator

Description

Hi, this issue is a follow up to #9869.

I recently tried using DeckGL again, after upgrading to the latest version which incorporates the fix by @Pessimistress on #10191.
I was surprised to find that the compilation error reported in this issue still occurs. I checked the minimal example for the proposed fix that is linked in #10069, for which I initially reported that it worked, but got the same compilation error.
I'm not sure how to explain that, but that must be my mistake in some way... I apologize for this, maybe I got mixed up between browsers when testing the example, I don't know.

I came up with a fix that is cleaner than my previous workaround (#10069) and uses shader inputs to define the NaN value.
The aggregation transform props already included a naN field, which was not used.
I am submitting a PR to close this issue. Sorry for the confusion !

Start with the reproduction and prior context in #9869 and the minimal example linked from #10069. Inspect the aggregation transform props, especially the existing naN field, and the shader inputs involved in the GPU aggregator; done means the compilation error no longer occurs in the reported DeckGL usage.
