C++20 deprecates capturing the this pointer via the '=' capture.
Instead, we replace it or extend the capture specification.

Hides the following options when the title id is 0:

Adds the following actions:

The introduction of multicore rendered this setting non-functional as timing code was changed.

This removes the setting entirely.

An empty QStringLiteral can more efficiently be replaced with an empty
QString.

Solves an issue with restoring the value upon reloading program.

Those are already found in the Filesystem tab.
They were added back to the Debug tab by mistake in the Vulkan PR.

If the user had cancelled, it would clear the text box. That behavior was sanitized underneath, but may anyways cause inconveniences.

This picks a default directory and file name. If on Windows and save-as screenshot saving is enabled, it asks the user, first defaulting to the default screenshot path, and with a default filename in the format `[title_id]_[year-mt-dy_hr-mn-sc-msc].png`. Otherwise, or on Linux for now, it simply saves a file in that directory with that file name.

This adds two options to the General -> UI tab. The first disables picking a place to save the file. The second chooses a default directory for saving screenshots.

These were only kept for compatibility with old code during testing.

Also gets rid of unnecessary explicit namespace usage.

Fixes a regression where the global config takes up a lot of extra space.

The way the configurations are set up, it is not trivial to do this. I'll leave it as is, but the API selection, and the background color and volume slider selectors are kind of not following the style.

Not a catch-all, but helps clean up the code for when I do this a lot. Also fixes some bugs caught in configure_graphics.

I noticed some of the code could be reduced to just passing the function an int, since I was doing the same thing over and over. Also clang-formats configure_graphics

Let's see if I make up my mind.

Also adds trackers for graphics and advanced graphics
