Use ForkJoinPool for the CPU-heavy executor. Using FJP for the CPU-heavy pool yields better wall time than ThreadPoolExecutor on machines with many cores. The previous regression found in the 72-core machine is no longer present. Benchmark results with flag value = HOST_CPUS showed: * 12 cores: -12.37% CPU, -8.88% wall * 16 cores: -5.82% CPU, +0.48% wall (~1s) * 72 cores: -2.98% CPU, +1.61% wall (~1s, statistically insignificant) PiperOrigin-RevId: 374620567
