Keep both sides in GuestSysmodule.cpp (the unknown id check and the Windows
unwind region checks) and in libSceSysmodule.md (Silent stubs and Functional).

sceSysmoduleIsLoaded, sceSysmoduleLoadModule and sceSysmoduleUnloadModule
return success for an id missing from the module table, because titles that
load or unload such an id aborted otherwise (b4db9fdd6, a2520aa07). Nothing
tested or recorded it, and two commented-out throws were left in the code.
Remove the commented-out throws, list the three functions under Silent stubs
in the library's technical debt file, and test that unknown ids succeed
without changing state while the internal variants still throw.

sceSysmoduleGetModuleInfoForUnwind called VirtualQuery and GetMappedFileNameA on every call. VirtualQuery on a large image section costs time proportional to the section (2 us for 16 KiB, 51 us for 8 MiB, 167 us for 32 MiB), and a title that unwinds exceptions while loading calls it for every frame of every throw.
The region and file name of an address inside an image of the Windows loader's module list are kept per region and used while the loader still reports the same image (base, time stamp and size). Other addresses are queried every time.
