* Implement a new physical memory manager and replace DeviceMemory * 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 * Address PR feedback * Fix build * Return a well defined value for GetPhysicalAddress with invalid VA, and do not return unmapped ranges as modified * Typo
