These functions come in a pair and are needed by Smash Ultimate, Minecraft, and Skyrim, amongst others.

This is supposed to return the current process' ID. (0 indicates an
invalid ID for both process IDs and ARU IDs).

This was causing some games (most notably Pokemon Quest) to softlock due to an event being fired when not supposed to. This also removes a hack wherein we were firing the state changed event when the game retrieves it, which is incorrect.

Changed logging to be "Log before execution", Added more error logging, all services should now log on some level

The interface for shared memory was changed, but another commit was
merged that relied on the (previously public) internals of SharedMemory.

This amends that discrepancy.

The accessor should be doing just that, accessing, rather than retaining
the lifetime of the data broker as well.

This cleans up most of the callbacks and such in the Applets::Applet interface, while also properly implementing all four data channels.

a

Allows the game to verify and send a message to the frontend.

Allows use of software keyboard applet and future applets to be easily added by adding enum ID and a switch case.

Now starts the applet provided in constructor.

Used by software keyboard applet for data transfer.

std::stack was no longer suitable for non-trivial operations

Needs to be accessible by applet files.

Writes to an AM::IStorage object through an IStorageAccessor will now be preserved once the accessor is destroyed.

Creates an AM::IStorage object with the contents of the transfer memory located at the handle provided.

Specifying an internal resolution in yuzu now will report the scaled changes to vi and am.

Started implementation of the AM message queue mainly used in state getters. Added the ability to switch docked mode whilst in game without stopping emulation. Also removed some things which shouldn't be labelled as stubs as they're implemented correctly

* get rid of boost::optional

* Remove optional references

* Use std::reference_wrapper for optional references

* Fix clang format

* Fix clang format part 2

* Adressed feedback

* Fix clang format and MacOS build

Now that we can actually use std::optional on macOS, we don't need to
continue using boost::optional here.
