Stub RequestUpdateAudioRenderer, StartAudioRenderer and StopAudioRenderer

GPU: Added a command processor to decode the GPU pushbuffers and forward the commands to their respective engines

Also moved the GPU MemoryManager class to video_core since it makes more sense for it to be there.

Several misc. VI fixes

More fixes for Libnx

- Another fix for libnx.

Various fixes for libnx, etc.

dynarmic: Fix bug due to Windows ABI mismatch

dynarmic: Update to 41ae12263

Changes: Primarily implementing more A64 instructions

nvdrv: Implement AllocateSpace and MapBufferEx

Service: stub some functions in am, audio, time, vi services

Service/hid: stub SetNpadHandheldActivationMode

Stubs for HID, AM, and a mutex fix

* FinishInitalize needed for 3.0.1+ games

* nvdrv:s and nvdrv:t both use NVDRV

* Most settings return 0 on hardware, disabled NV_MEMORY_PROFILER for now.

NVN_THROUGH_OPENGL & NVRM_GPU_PREVENT_USE are a few interesting settings to look at. Carefully choosing settings can help with drawing graphics later on

* Initial /dev/nvhost-gpu support

* ZCullBind

* Stubbed SetErrorNotifier

* Fixed SetErrorNotifier log, Added SetChannelPriority

* Allocate GPFIFO Ex2, Allocate Obj Ctx, Submit GPFIFO

* oops

* Fixed up naming/structs/enums. Used vector instead of array for "gpfifo_entry"

* Added missing fixes

* /dev/nvhost-ctrl-gpu

* unneeded struct

* Forgot u32 in enum class

* Automatic descriptor swapping for ioctls, fixed nvgpu_gpu_get_tpc_masks_args being incorrect size

* nvdrv#QueryEvent

* Renamed logs for nvdrv

* Refactor ioctl so nv_result isn't needed

* /dev/nvhost-as-gpu

* Fixed Log service naming, CtxObjects now u32, renamed all structs, added static_asserts to structs, used INSERT_PADDING_WORDS instead of u32s

* nvdevices now uses "Ioctl" union,

* IoctlGpfifoEntry now uses bit field

* final changes
