zx_status_t EnumerateProcessorLocalApics (const AcpiParserInterface & parser, const fit::inline_function<zx_status_t (const AcpiMadtLocalApicEntry &)> & callback)
```
Enumerate all enabled Processor Local APICs in the system, calling

|callback| once for each.

Each entry corresponds to an entry in the ACPI MADT table of type "Local

Apic". See ACPI v6.3 Section 5.2.12.2 for details.

|callback| is invoked once for each entry. The function returns any error

returned by the callback, or if an error was found attempting to parse the

tables.
