FSUI: Formatting

[TheLastRar]

Description of Changes

Format FullscreenUI, again

Rationale behind Changes

In #12366, I had formatted this file after getting frustrated with how similar lines where formatted in 3 different ways.
With the exception of 3 string arrays got as collateral, clangformat matched the existing code
It was, however, determined that the existing code was not formatted as nice as we would like.
While we can't precisely configure clangformat's behaviour here, it was found that adding a trailing , mostly gets the desired behaviour.

Also, re-adds a space that was removed in #12369, I'm unsure why it was removed so RFC here.

Suggested Testing Steps

Is the code visually better looking

[TheLastRar]

There are a couple sections of code where we have a multiline list with multiple elements on the same line Like here;

pcsx2/pcsx2/ImGui/FullscreenUI.cpp

Lines 2921 to 2925 in 9996061

	static constexpr const char* titles[] = {FSUI_NSTR("Summary"), FSUI_NSTR("Interface Settings"), FSUI_NSTR("BIOS Settings"),
	FSUI_NSTR("Emulation Settings"), FSUI_NSTR("Graphics Settings"), FSUI_NSTR("Audio Settings"), FSUI_NSTR("Memory Card Settings"),
	FSUI_NSTR("Controller Settings"), FSUI_NSTR("Hotkey Settings"), FSUI_NSTR("Achievements Settings"),
	FSUI_NSTR("Folder Settings"), FSUI_NSTR("Advanced Settings"), FSUI_NSTR("Patches"), FSUI_NSTR("Cheats"),
	FSUI_NSTR("Game Fixes")};

Adding a trailing comma will cause clang-format to put each element on its own line, Is that preferable to the current form?

Currently I have left them as is, as they had been untouched in my prior format commit

I would prefer that.
