voice-proto: dump module events, wake sync waiter on unlisted results

Browse source 
- apm_callback: hexdump APM_EVENT_MODULE_TO_CLIENT (0x03001000) packets
  so module events (e.g. VCPM's) are visible in dmesg if delivered.
- GPR_BASIC_RSP_RESULT default case now records the result and wakes the
  waiter: probe opcodes sent via voice-proto (REGISTER_MODULE_EVENTS,
  future ones) get their DSP error immediately instead of stalling for
  the full command timeout.
