feat(libs): provide the exports PPSA01289 imports that no library has

Sackboy: A Big Adventure (PPSA01289) imports nine functions that no library
exports, so eager binding fails before it starts.

- libSceVoiceChat: sceVoiceChatRequestLeaveVoiceChatGroup and
  sceVoiceChatRequestDeleteVoiceChatGroup, offline requests like the other
  sceVoiceChatRequest* calls
- libSceNpSessionSignaling: sceNpSessionSignalingGetConnectionFromPeerAddress,
  a throwing stub; the signature is unknown
- libSceCdlgG2P, a new library: the six sceG2PDialog* functions, throwing
  stubs declared without parameters

TechnicalDebt records the assumed and unknown signatures.
