Allows some implementations to avoid completely zeroing out the internal
buffer of the optional, and instead only set the validity byte within
the structure.
This also makes it consistent how we return empty optionals.

* ArmInterface: return ref instead of copy for GetTimer
* ArmInterface: add const ref GetTimer
* ArmInterface: return raw pointer instead of shared_ptr in GetTimer
* remove more unnecessary shared_ptr usage
* Fix save states
* fix unit tests
* Kernel/Process: Notify the CPUs that a new pagetable has been set every time the process they're executing changes.
Previously the page table would only be changed when the current CPU's page table was changed, this lead to stale JIT states and the PC going to 0 when context-switching a different core inside the ThreadManager::SwitchContext function because the JIT for a new pagetable is only constructed upon receiving the change notification.
* Kernel/Process: Use the relevant CPU's last process to determine when to switch its current process.
Previously it was checking the kernel's current_process variable, which gets overwritten every time a CPU runs its slice. The rescheduling happens after all CPUs have run their slice so the code was effectively only checking the last CPU's process.
* vm_manager: Handle multiple areas in ChangeMemoryState
It is possible that a few areas have the same permisson and state, but with different backing pointers. Currently, this function assumes that only one continous area is found, but this is not always the case.
* service/ldr_ro: Handle multiple areas in VerifyBufferState
It is possible that the buffer passed from the game is made up of multiple areas with the same permisson and state but different backing pointers. Change the check to allow that.
* Core::Timing: Add multiple timer, one for each core
* revert clang-format; work on tests for CoreTiming
* Kernel:: Add support for multiple cores, asserts in HandleSyncRequest because Thread->status == WaitIPC
* Add some TRACE_LOGs
* fix tests
* make some adjustments to qt-debugger, cheats and gdbstub(probably still broken)
* Make ARM_Interface::id private, rework ARM_Interface ctor
* ReRename TimingManager to Timing for smaler diff
* addressed review comments
