* Make HLE disposable safely This fix the oldest issue with the HLE code: the kernel side disposability. Changelog: - Implement KProcess::UnpauseAndTerminateAllThreadsExcept, KThread::Terminate, KThread::TerminateCurrentProcess, KThread::PrepareForTermiation and the svc post handler accurately. - Implement svcTerminateProcess and svcExitProcess. (both untested) - Fix KHandleTable::Destroy not decrementing refcount of all objects stored in the table. - Spawn a custom KProcess with the maximum priority to terminate every guest KProcess. (terminating kernel emulation safely) - General system stability improvements to enhance the user's experience. * Fix a typo in a comment in KProcess.cs * Address gdk's comments
