Libraries: Implement sceKernelIsInSandbox, update OrbisSysModule enum (#3546)

Browse Source 
* Implement sceKernelIsInSandbox

libSceSysmodule uses this to determine if it should use sceKernelGetFsSandboxRandomWord or just hardcode "system" for retrieving modules.
Also changes some function types to use our types.

* Update OrbisSysModule enum

Adds missing values based on library testing.

* Clang
