* Haydn: Part 1

Based on my reverse of audio 11.0.0.

As always, core implementation under LGPLv3 for the same reasons as for Amadeus.

This place the bases of a more flexible audio system while making audout & audin accurate.

This have the following improvements:
- Complete reimplementation of audout and audin.
- Audin currently only have a dummy backend.
- Dramatically reduce CPU usage by up to 50% in common cases (SoundIO and OpenAL).
- Audio Renderer now can output to 5.1 devices when supported.
- Audio Renderer init its backend on demand instead of keeping two up all the time.
- All backends implementation are now in their own project.
- Ryujinx.Audio.Renderer was renamed Ryujinx.Audio and was refactored because of this.

As a note, games having issues with OpenAL haven't improved and will not
because of OpenAL design (stopping when buffers finish playing causing
possible audio "pops" when buffers are very small).

* Fix for applet transfer memory + some nits

* Keep handles if possible to avoid server handle table exhaustion

* Fix IPC ZeroFill bug

* am: Correctly implement CreateManagedDisplayLayer and implement CreateManagedDisplaySeparableLayer

CreateManagedDisplaySeparableLayer is requires since 10.x+ when appletResourceUserId != 0

* Make it exit properly

* Make ServiceNotImplementedException show the full message again

* Allow yielding execution to avoid starving other threads

* Only wait if active

* Merge IVirtualMemoryManager and IAddressSpaceManager

This fix reverb 3d mono rendering using -1 instead of 1 for delay line
offset.

I also did some clean up as this value is now used by all channel
variants.

Now Resident Evil 6 goes in-gane.

This fix an underflow in the setup of delay time in the delay effect.

THis fix a regression caused by Amadeus on Shovel Knight: Treasure
Trove.

This add a missing offset on the output buffer of the DataSourceVersion2Command.

This fix music only playing on the left channel on Fairy Tail, Family Mysteries: Poisonous Promises, SEGA AGES Sonic the Hedgehog 2 and probably more.

This project wasn't really used by anyone and isn't worth mantaining.

This commit remove the profiler entirely from Ryujinx and remove the associated CI tasks.

This fix front center and lfe being inverted in input of the
DownMixSurroundToStereoCommand.

This fix:
- Voices being missing on FE3H videos
- Mario Tennis Aces missing backgroun
- Probably more.
