Henrik Rydgård c4160b4eed HLE: Small kernel cleanups
Initialize the wokeThreads locals that were passed by reference uninitialized in
the event flag, VPL and semaphore timeout handlers. Harmless today since the
callee only ever assigns to them, but every other use in the same files starts
at false.

Do the semaphore overflow check in 64-bit, so a large signal value can't wrap
past it into currentCount.

Henrik Rydgård 0f94e01241 HLE: Clamp the wait timeout remaining time to zero
CoreTiming::UnscheduleEvent returns the scheduled time minus the current time,
which is negative when the event is overdue but hasn't been processed yet - the
exact situation when a wait is satisfied right around its own timeout. Only the
semaphore clamped it; everywhere else we wrote (u32)cyclesToUs(negative) into
the game's timeout variable, i.e. a huge bogus "remaining time".

Pulled the shared shape into HLEKernel::WriteRemainingTimeout so it can't drift
apart again - event flags, mbx, fpl, vpl, msgpipe, mutex, lwmutex and semaphore
all go through it now. The two thread-end sites keep their own copy since they
unschedule even when the game passed no timeout pointer, and sceUsb just gets
the clamp.

Henrik RydgårdandClaude Sonnet 5 21b7ce7392 Expose EventFlag/Mutex/Semaphore/MsgPipe/Callback in their headers
These KernelObject subclasses (and their Native* status structs) were
private implementation details of their respective .cpp files. Move them
into the matching .h instead, so external code - specifically the upcoming
WebSocket kernel-object introspection endpoints - can read a live object's
state directly via kernelObjects.Get<T>()/Iterate<T>(), the same way
PSPModule/PSPThread already can. Read-only by convention: nothing outside
each file should call DoState() or otherwise mutate these; the fields are
public here for that file's own pre-existing use, not an invitation to
write from elsewhere.

To avoid pulling each type's full dependency set (Memory::, BlockAllocator,
CoreTiming, HLEKernel::...) into headers many other files include, non-trivial
method bodies (DoState, and MsgPipe's buffer/wait-list management) are
declared in the header but still defined out-of-line in the .cpp, same as
before - only genuinely trivial one-liners went inline.

KernelObjectPool also gains IterateAll(), a type-agnostic sibling of the
existing Iterate<T>() - walks every live kernel object regardless of type,
for a coarse "what's alive right now" overview.

No behavior change - this is a pure visibility/declaration-vs-definition
move, not new functionality. That lands in a follow-up commit.

Unknown W. Brackets ccd4e92184 Kernel: Use PSPPointer for status objects.
Code makes more sense when reading ->size rather than offset 0.
