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.

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.
* Add draft sceKernelFindModuleByUID
#13205
* Add KERNEL_SYSCALL flag
* oop
* oop2
* Not sure why make this change before
* Last night I might be too tried
This tries to execute them within the context of the emulator as much as
possible, so we don't have weird bugs. Going with a file type so we can
easily load the dump by opening the file directly.
Couldn't think of a better way to do this, maybe there's some fancy
one I don't know about.
Also finished up a couple left over kernel objects.
Maybe a quarter the way there?
