juanpimg 2f0ed638dc feat(prx): declare the missing PS5 3.20 system exports
AnyPS5 resolves a title's imports by NID, so a title that imports a system
function no library provides fails to load with an unresolved import. The
PS5 3.20 export inventory lists 193 such exports across 37 PS5 system
libraries AnyPS5 implements but does not provide.

Declare them as throwing stubs so those titles load and reach their next
blocker. Each declaration calls NotImplemented_nid_no_patch and returns 0;
none of them implements the function. Declarations with a credible
prototype use it and cite the source with a pinned commit, and the rest
are declared without parameters, which resolves the import without making
an ABI claim. The technical-debt files record the limitation per library.

libSceMbus and libSceSystemService are left out because pull request #7821
declares them. libSceAgc is left out because its exports are versioned, so
the 3.20 NID names a different symbol from the one AnyPS5 ships.
libSceAvPlayer.native is left out because it compiles libSceAvPlayer's
Export.cpp.

Names and NIDs come from the PS5 3.20 export inventory at

# libSceNpSessionSignaling technical debt
### Unknown function info
- [sceNpSessionSignalingGetConnectionFromPeerAddress](../../../core/libs/prx/libSceNpSessionSignaling/Export.cpp) (libSceNpSessionSignaling) - imported by PPSA01289 and added without an implementation; unknown signature
- [sceNpSessionSignalingGetMemoryInfo](../../../core/libs/prx/libSceNpSessionSignaling/Export.cpp) (libSceNpSessionSignaling) - unknown signature
- [sceNpSessionSignalingGetConnectionStatistics](../../../core/libs/prx/libSceNpSessionSignaling/Export.cpp) (libSceNpSessionSignaling) - unknown signature
- [sceNpSessionSignalingGetConnectionStatus](../../../core/libs/prx/libSceNpSessionSignaling/Export.cpp) (libSceNpSessionSignaling) - `(int32 context id, int32 connection id, int32* status, SceNetInAddr* peer address, uint16* peer port)` is ASTRO BOT's (PPSA21564 01.007.000) call at 0x30622B: the context id from a 32-bit field, the connection id, three stack outputs, a negative result taken as an error, then the address passed to `sceNetInetNtop(AF_INET, ...)` and the port to `sceNetNtohs`. It matches PS4's `sceNpSignalingGetConnectionStatus`. The title reaches it only for a connection id from the signaling library, which offline never hands one out. No session ever activates offline, so every connection id answers `CONN_NOT_FOUND` (0x8055330C, from [shadPS4](https://github.com/shadps4-emu/shadPS4/blob/64d198190fa05d37cbb1fa29c50f967c376fce55/src/core/libraries/np/np_error.h)) without writing the outputs, and a null status answers `INVALID_ARGUMENT`. The context id is not checked, as contexts are not tracked. The console's answer for an unknown context or connection is unverified
- PPSA31327 imports declared without parameters, signatures unknown: [sceNpSessionSignalingGetGroupInfo, sceNpSessionSignalingGetConnectionFromNetAddress2](../../../core/libs/prx/libSceNpSessionSignaling/Export.cpp) (libSceNpSessionSignaling), imported by Yakuza 0 Director's Cut and not called before the main menu.
- [sceNpSessionSignalingCreateJoinActivate, sceNpSessionSignalingGetConnectionFromNetAddress, sceNpSessionSignalingGetCustomProperty, sceNpSessionSignalingGetGroupFromPeerAddress, sceNpSessionSignalingInitializeWithPort, sceNpSessionSignalingJoinActivate and sceNpSessionSignalingSetCustomProperty](../../../core/libs/prx/libSceNpSessionSignaling/Export.cpp) (libSceNpSessionSignaling) - names and NIDs are present in the [PS5 3.20 export inventory](https://github.com/DNNDHH/PS5-3.20_Libs/blob/b2a77c09cd71c01f34c790cfbe98c751a13262ad/libSceNpSessionSignaling.c), but no credible prototypes were found. They are declared without parameters solely to resolve known imports; this is not an ABI claim.
