Adjust default Netty receive predictor size to 64k (#23542) 

With this commit we change the default receive predictor size for Netty
from 32kB to 64kB as our testing has shown that this leads to less
allocations on smaller heaps like the default out of the box
configuration and this value also works reasonably well for larger
heaps.

Closes #23185
