Implement Emulator::GracefulShutdown()

Addresses #11397

I think "graceful" is better word, very strange to use "merciful" in computing.

[Megamouse]

I think simply something like RequestShutdown wouldn't be too weird either

[Darkhost1999]

Lol. C'mon guys. There's plenty of memes in the code like the last of Arse and other Easter eggs. Let's be merciful when killing a process.

[elad335]

"Request" implies the ability to refuse, I choose "graceful".

This build seems to cause RPCS3 to crash. It also does not behave the same way as sending the exit CMD.

you basically have to exit gracefully whenever you first call Kill during some user interaction (after GetBootConfirmation)

[Megamouse]

We most likely need a flag that tells us if we're still compiling at the beginning, so that graceful shutdown can just kill right away.
Otherwise it will be a pain in the ass to figure this out on every single occasion

This is already done by checking the send call in GraceFulShutdown, so it's probably safe to simply call GraceFulShutdown instead of kill in the gui

I suggest adding a blocking MainWindow wrapper that simply calls (GracefulExit + ProcessEvents loop) and using that instead of the Kill calls that I pointed out

please only do new commits until we merge.
I don't want to re-read all the code again ^^

I think the only part that's wrong now is the GetBootConfirmation I mentioned earlier. (If you decline then it will spawn a new one right away).

After that is sorted out, I'll actuallly test it ;)

[Megamouse]

K I'll test tomorrow

[Megamouse]

lgtm I guess. The TODO seems curious, but I'll merge if that's not a blocker
