Implement beatmap options popover

[Joehuu]

• Closes BeatmapOptionsOverlay is missing new design #24273
• Addresses `BeatmapOptionsButton` text being split per line causes issues in other languages #22767

Some differences to the proposed design:

• no arrow (to make things simple/consistent as no other popover has it yet)
• there were inconsistent measurements so I did my best to find the average/best numbers
• button sorting hasn't changed because of keys being assigned by index (muscle memory)
• icons were unchanged from old design (i.e. trash) as the design claims that it is using the same icons the game currently uses (see top on figma)

I had to take a different approach to add the buttons to the popover content since popovers are reconstructed every time.

The old BeatmapOptionsOverlay had SongSelect adding the buttons, and if you wanted to make an isolated test scene, you would have to copy the adding logic. It is now local by using DI.

Here's a WIP branch for the footer integrated into the game: master...Joehuu:osu:footer-redesign

I saw in the GIF that it says "rewind" when you hold shift (for when you're rewinding random). I think this should also change the icon to better signify that. (it isn't in the Figma, but it would be a nice addition)

Not sure about having "general" in so many places for translation.

osu/osu.Game/Localisation/GameplaySettingsStrings.cs

Line 25 in 95a9b53

public static LocalisableString GeneralHeader => new TranslatableString(getKey(@"general_header"), @"General");

is at least one other example.

Maybe these should be in the general localisations as a single string?
