hw/core/machine: Add missing 'units.h' and 'error-report.h' headers

Include the missing "qemu/units.h" to fix when refactoring code:

  ../hw/core/machine.c:743:34: error: use of undeclared identifier 'MiB'
  743 |     mc->default_ram_size = 128 * MiB;
      |                                  ^
  ../hw/core/machine.c:750:44: error: use of undeclared identifier 'TiB'
  750 |     mc->smbios_memory_device_size = 2047 * TiB;
      |                                            ^

and "qemu/error-report.h" to fix:

  ../hw/core/machine.c:1029:13: error: call to undeclared function 'error_report' [-Wimplicit-function-declaration]
 1029 |             error_report("NUMA node %" PRIu16 " is missing, use "
      |             ^
  ../hw/core/machine.c:1240:9: error: call to undeclared function 'warn_report' [-Wimplicit-function-declaration]
 1240 |         warn_report("CPU model %s is deprecated -- %s",
      |         ^
