Implement sceKernelGetModuleInfo, sceKernelGetModuleInfoInternal, and sceKernelGetModuleList (#2850)

Browse Source 
* Fix GetModule exception

Simple mistake

* Prevent OOB writes in add_segment

Due to mistakes in our linker logic, OpenOrbis' libSceFios2 causes OOB writes here.
While the ideal solution would be to fix the erroneous behavior, the best I'm capable of right now is just preventing the OOB writes.

* Implement sceKernelGetModuleInfo, sceKernelGetModuleInfoInternal, sceKernelGetModuleList

These are implemented based on hardware observations and a homebrew sample made by red_prig. I've yet to test what error cases can show up.

* Clang

* Accurate error returns

If there are more modules than provided space, then return kernel ENOMEM.
If either handles or out_count are null, return kernel EFAULT.

* Accurate error checks in ModuleInfo functions

* Clang
