Adds SceKernelLoadExecVSHParam (matching JPCSP's reference layout - its
first four fields line up with the existing SceKernelLoadExecParam,
which is why the plain sceKernelLoadExec already worked for
sceKernelLoadExecVSHMs2) and fills in the rest of LoadExecForKernel's
NIDs from JPCSP: real implementations for sceKernelExitVSHVSH/Kernel
(mirrors sceKernelExitGame) and sceKernelLoadExecBufferVSHUsbWlan (loads
an exec from an in-RAM buffer instead of a file - the VSH's "push a game
over USB/WLAN" path), plus UNIMPL stubs for everything JPCSP itself only
knows by NID.
sceKernelLoadExecBufferVSHUsbWlan needed __KernelLoadExec split into a
file-reading front end and a shared __KernelLoadExecFromPtr back end
that both it and the new buffer-based path call into - a pure
extract-method refactor of the single most heavily used boot path in the
emulator. Verified no regression: same 11 passed / 9 pre-existing-failed
split on pspautotests/tests/cpu/*, and loader/bss still passes, before
and after this change.

prefersStatusBarHidden was dead code - it computed an orientation and a
(commented out) user preference, then unconditionally returned false. So the
status bar was only ever hidden on iPhone in landscape, and only because iOS
does that on its own in compact height.
Now it honors bImmersiveMode from the DisplayLayoutConfig matching the current
orientation, so it also applies in portrait and on iPad. Adds the corresponding
checkbox to the iOS system settings, and updates the status bar on rotation and
when the setting is toggled.
Also fixes a missing break in the ROTATE_UPDATED case in System_Notify, and a
static/non-static mismatch on sceKernelLoadModuleBufferUsbWlan that broke the
build (the header intentionally exposes it for sceVshBridge).

nm.nsegment is attacker-controlled but segmentaddr/segmentsize are fixed
4-entry arrays; the debug info loop read past them. Clamp to 4 like the
other consumers.
The import debug reporter used IsValidAddress (start-address only) before
formatting module names with %s, so a crafted unterminated name could be
read past guest RAM. Use IsValidNullTerminatedString instead.
Added KernelModuleAddressDescription() (Core/HLE/sceKernelModule.cpp),
which looks up which currently loaded module (and text/data/bss/segment
section within it) an address falls in, e.g. "EBOOT.BIN.text+1234".
Wired it into:
- Core_MemoryException/Core_ExecException/Core_BreakException
(Core/Core.cpp), appended next to every address/pc/ra shown in their
log lines.
- FormatStackTrace (Core/MemFault.cpp), appended per-frame next to the
existing symbol description.
This makes crash/exception logs actionable even when there's no symbol
at the faulting address - you at least get which module and section
it's in, useful for reverse engineering unfamiliar code.
Verified live via headless: injected a MIPS break instruction at the
current PC (through Tools/wsdbg) and confirmed the log line changed from
"break instruction hit at 088040ac" to "break instruction hit at 088040ac
[sceDisplayWaitVblank Test.text+ac]".

A call through a still-pending import gets written as a generic "invalid
syscall" opcode (WriteFuncMissingStub) that no longer carries the
original module name or NID by the time it's actually invoked - but the
address of the syscall instruction itself is exactly the stubAddr every
pending FuncSymbolImport already records. Added
KernelFindImportByStubAddr() to search loaded modules' importedFuncs for
a match, and use it in GetSyscallFuncPointer's unknown-syscall path.

Driver 76 uses sceKernelGetModuleIdList to get a module list
after calling sceUtilityLoadNetModule, then go module by module
with sceKernelQueryModuleInfo to check if at least pspnet_adhoc.prx
was loaded.
Load modules during sceUtilityLoadNetModule, expand success lying
modules to have real names, add adhoc modules to the success lying
list, list lied modules during sceKernelGetModuleIdList.
By fixing up badly aligned addresses in HLESubscriber.cpp.
This should help eliminate any bad usage within PPSSPP itself, while
also keeping existing websocket code working.
Additionally, this makes some end addresses exclusive instead of
inclusive, which simplifies address math.
