[vm] Reduce maximum new generation size and growth rate.

For example, by default 64-bit architectures now grow as 2, 4, 8, 16 instead of 2, 8, 32.

This change is to reduce memory usage and maximum minor GC time for Flutter and Fuchsia.
It would negatively impact batch applications, which prefer throughput,
so the new defaults are overriden by the command-line Dart VM in
runtime/bin/main.cc
