Implement GPU syncpoints (#980)
* Implement GPU syncpoints

This adds support for GPU syncpoints on the GPU backend & nvservices.

Everything that was implemented here is based on my researches,
hardware testing of the GM20B and reversing of nvservices (8.1.0).

Thanks to @fincs for the informations about some behaviours of the pusher
and for the initial informations about syncpoints.

* syncpoint: address gdkchan's comments

* Add some missing logic to handle SubmitGpfifo correctly

* Handle the NV event API correctly

* evnt => hostEvent

* Finish addressing gdkchan's comments

* nvservices: write the output buffer even when an error is returned

* dma pusher: Implemnet prefetch barrier

lso fix when the commands should be prefetch.

* Partially fix prefetch barrier

* Add a missing syncpoint check in QueryEvent of NvHostSyncPt

* Address Ac_K's comments and fix GetSyncpoint for ChannelResourcePolicy == Channel

* fix SyncptWait & SyncptWaitEx cmds logic

* Address ripinperi's comments

* Address gdkchan's comments

* Move user event management to the control channel

* Fix mm implementation, nvdec works again

* Address ripinperi's comments

* Address gdkchan's comments

* Implement nvhost-ctrl close accurately + make nvservices dispose channels when stopping the emulator

* Fix typo in MultiMediaOperationType

9426ef3f06 Rewrite nvservices (#800)
* Start rewriting nvservices internals

TODO:

- nvgpu device interface
- nvhost generic device interface

* Some clean up and fixes

- Make sure to remove the fd of a closed channel.
- NvFileDevice now doesn't implement Disposable as it was never used.
- Rename NvHostCtrlGetConfigurationArgument to GetConfigurationArguments
to follow calling convention.
- Make sure to check every ioctls magic.

* Finalize migration for ioctl standard variant

TODO: ioctl2 migration

* Implement SubmitGpfifoEx and fix nvdec

* Implement Ioctl3

* Implement some ioctl3 required by recent games

* Remove unused code and outdated comments

* Return valid event handles with QueryEvent

Also add an exception for unimplemented event ids.

This commit doesn't implement accurately the events, this only define
different events for different event ids.

* Rename all occurance of FileDevice to DeviceFile

* Restub SetClientPid to not cause regressions

* Address comments

* Remove GlobalStateTable

* Address comments

* Align variables in ioctl3

* Some missing alignments

* GetVaRegionsArguments realign

* Make Owner public in NvDeviceFile

* Address LDj3SNuD's comments
