    vm: centralize VM_BATCHQUEUE_SIZE definition
    
    Remove the platform-specific definitions of VM_BATCHQUEUE_SIZE
    for amd64 and powerpc64, and instead treat all 64-bit platforms
    identically.  This has the effect of increasing the arm64
    and riscv VM_BATCHQUEUE_SIZE to match that of other platforms.
