fix(libSceUserService): report the console's default accessibility settings 

On a PS5 (firmware 13.60) a user with every accessibility setting at
its default reads chat transcription 0, press-and-hold delay 0, trigger
effect 1, vibration 1, zoom 0 and zoom follow focus 1; all six read 0
here. A user who is not logged in returns 0x80960009 with or without an
output, as sceUserServiceGetAgeLevel does.

- [sceUserServiceGetAgeLevel](../../core/libs/prx/libSceUserService/Export.cpp) (libSceUserService) - on a PS5 (firmware 13.60) the value is the age set in the user's parental restriction (0, 7, 12 and 15 were measured) and `0xFFFFFFFF` without one; a user who is not logged in returns `0x80960009` with or without an output. Parental restrictions are not modelled, so the initial user is always reported as unrestricted. PPSA12544 (Unity) only stores the value for its user profile

What each number means is unknown. A user who is not logged in returns `0x80960009` with or without an output
- [sceGameUpdateGetAddcontLatestVersion](../../core/libs/prx/libSceGameUpdate/Export.cpp) (libSceGameUpdate) - a null `entitlement_label` throws: KytyPS5 accepts it, prosper returns `0x80412803`. Bytes after `found` are zeroed as in KytyPS5; prosper leaves them untouched
- [sceSystemServiceParamGetString](../../core/libs/prx/libSceSystemService/Export.cpp) (libSceSystemService) - the system name (parameter 6) is the fixed `PS5`, not the console's name; other parameters and buffers of 1 to 64 bytes throw
