* Proper generic constraints

* Fix debug build

* Add memory tests

* New CPU memory manager and general code cleanup

* Remove host memory management from CPU project, use Ryujinx.Memory instead

* Fix tests

* Document exceptions on MemoryBlock

* Fix leak on unix memory allocation

* Proper disposal of some objects on tests

* Fix JitCache not being set as initialized

* GetRef without checks for 8-bits and 16-bits CAS

* Add MemoryBlock destructor

* Throw in separate method to improve codegen

* Address PR feedback

* QueryModified improvements

* Fix memory write tracking not marking all pages as modified in some cases

* Simplify MarkRegionAsModified

* Remove XML doc for ghost param

* Add back optimization to avoid useless buffer updates

* Add Ryujinx.Cpu project, move MemoryManager there and remove MemoryBlockWrapper

* Some nits

* Do not perform address translation when size is 0

* Address PR feedback and format NativeInterface class

* Remove ghost parameter description

* Update Ryujinx.Cpu to .NET Core 3.1
