* 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
