pc: acpi: drop intermediate PCMachineState.node_cpu

PCMachineState.node_cpu was used for mapping APIC ID
to numa node id as CPU entries in SRAT used to be
built on sparse APIC ID bitmap (up to apic_id_limit).
However since commit
  5803fce pc: acpi: SRAT: create only valid processor lapic entries
CPU entries in SRAT aren't build using apic bitmap
but using 0..maxcpus index instead which is also used
for creating numa_info[x].node_cpu map.
So instead of doing useless intermediate conversion from
  1. node by cpu index -> node by apic id
       i.e. numa_info[x].node_cpu -> PCMachineState.node_cpu
  2. apic id -> srat entry PMX
       PCMachineState.node_cpu[apic id] -> PMX value
use numa_info[x].node_cpu map directly like ARM does and do
  1. numa_info[x].node_cpu -> PMX value using index
     in range 0..maxcpus
and drop not necessary PCMachineState.node_cpu and related
code.

That also removes the last (not counting legacy hotplug)
dependency of ACPI code on apic_id_limit and need to allocate
huge sparse PCMachineState.node_cpu array in case of 32-bit
APIC IDs.
