Initializing GraphicsWindow layout & children requires cooperation from
the graphics stack: on my system, for example, it causes a Vulkan
context to get created in order to get driver info. This is a slow
operation, and right now it is taking about 60-70% of the Dolphin
startup time on my system.
Move instead to a lazy-initialization model where the constructor
does nothing, instead offloading work to a separate Initialize() method
called before the window is shown.
I would expect this should be done for other larger parts of the UI,
especially the ones where creating widgets ends up triggering large IO
subsystems (I suspect controller configuration might be doing that).
(I'm not super happy with how this is implemented, but right now it's a
one-off, and it's a major complaint users have with the new UI. I
prioritized getting something working quickly...)
This makes it much more straightforward to access WiimoteDevice
instances and also keeps the implementation details of accessing those
instances in one spot.
Given as all external accesses to the WiimoteDevice instances go through
this function, we can make the other two private.
If we don't do this the prompt *may* appear behind the fullscreened window
and thus cause confusion. This happens both with exclusive fullscreen and
borderless fullscreen (e.g. for OpenGL).
This fixes 2 crashes with the pause function. One is when spamming the pause hotkey and the other is to press pause and step hotkeys at the same time. It does disable the screensaver getting disabled when the emulator is running, but paused, though, a better solution would have to be done without introducing these crashes.
It only needs to be updated when we changes the symbols, not every time the code widget updates and it does take a while to update them so this fixes some delay when updating the code window.
