kernel: A bit of refactoring and fix GetThreadContext3 correctness (#3042)

* Start refactoring kernel a bit and import some changes from kernel decoupling PR

* kernel: Put output always at the start in Syscall functions

* kernel: Rewrite GetThreadContext3 to use a structure and to be accurate

* kernel: make KernelTransfer use generic types and simplify

* Fix some warning and do not use getters on MemoryInfo

* Address gdkchan's comment

* GetThreadContext3: use correct pause flag
