[Feature Request] Grid layout for games in the library tab

[Foul-Tarnished]

It would be cool to have a grid layout for our games, in the library tab of SKIF.

The games icon would not be great for that, so it would be best if SKIF automatically take the most used grid from SteamGridDB
or instead use a standard grid picture for all games missing one, until the user change them manually

Would be even better if we could change the number of games per grid and row, to show more or less games (at different size)

Here's a basic mockup I did:

A few improvements that could be made:

• Better bottom part (SKIF infos about the profile, SK version, platform, etc)
• better search bar (longer ?) and better aligned
• bigger margins on the outside (left and right specifically), smaller margin between games
• Remove the play button altogether ? (because we launch by just clicking the game icon?)

For scrolling, either make the GUI "snap" for each row when we scroll, or let a smooth scrolling and make a gradient transparency on the bottom row that's being cut
