Create vector Wii and Gamecube icons and re-import default android icons as vector graphics. Scales better on a greater range of devices and takes up less space.

Android: Inherit from Material 3 themes and round corners on box art

Use large card view rounded corner guidelines

Fix action bar theming

Needed to import android back button clip art to fix material 3 theming issue. The DolphinSettingsBase style used to inherit from the Theme.MaterialComponents.DayNight.DarkActionBar theme which would provide the light text and icons but this is no longer available with Material 3.

Fit box art more snugly in CardView

Change card height to match cover art

Add padding to top of games list recyclerview

Update Onscreen Buttons Opacity and Adjust Default Opacity Setting

Basically, instead of having one button for config, one button
for graphics settings and so on, we now have just one settings
button which takes you to a screen where you pick between
config/graphics/GameCube controllers/Wii Remotes.

The main reason I want to do this is because people still have
trouble finding Overlay Controls in the "new" in-game menu.
Typically (depending on the screen size and the length of the
game name), the scrollable part of the menu can fit 4 items,
and merging Config and Graphics Settings into one item would
move Overlay Controls from 5th place to 4th place (assuming the
user doesn't have savestates enabled), which makes it findable
even for users who don't realize the menu can be scrolled.

The dialog that's shown when long pressing a game in the game
list is also shortened. While not a pressing matter, I think
it was getting a bit long.

An additional reason to do this is because we probably will
want to make it possible to edit the controller settings
from the in-game menu at some point in the future. With the
old approach, this would require us to dedicate a whopping 4
menu items just for settings (not including Overlay Controls),
which I think is excessive.
