libSceSystemLogger technical debt

sceSystemLoggerInitialize, sceSystemLoggerSetLogData and sceSystemLoggerTerminate (libSceSystemLogger) - the state and argument checks follow firmware 11.00's libSceSystemLogger.sprx disassembly, not measurements on a console: Initialize returns 0x81080005 when the library is already initialized, Terminate returns 0x81080004 when it is not, and SetLogData rejects a tag longer than 15 bytes or containing a character outside [0-9A-Za-z], a count above 32, a non-zero count with a null data pointer, an entry size above 64 and any non-zero byte in the entry's 32-byte tail. The entries are written to the host's standard error with the tag. The system logger service, its ring buffer and transport, the objects created by the firmware's internal initialize/terminate/submit helpers and the 0x81080001 failure paths are not implemented, so initialization always succeeds and submission always reports success. The tag is copied up to 15 bytes; the wrapper does not read its fourth argument register.
