Core timing 2.0 (#4913)

* 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
