Add map protection to tournament overlay

[ILW8]

This pull request adds "protects" to the tournament overlay. The upcoming MWC7K among other world cups and community tournaments have a protect system in their rulesets.

A protected map is indicated by a badge in the beatmap panel's top right corner with the color of the team that protected the map both in the mappool screen and in the gameplay screen. A shield icon was originally suggested in #24336 (comment), and FontAwesome is the only convenient shield icon I could find. Eventually, we could ask the world cups design team to make a fitting custom icon or allow users to provide their own images, much like how it's done with the mod icons.

Setting up mappools/protects:

• the number of protects is set per pool, with 0 meaning protects are disabled ¹
• the protect phase takes place before the ban phase starts (if applicable)
• a protected map cannot be banned by the opposing team
• a protected map can be picked by either team, unless "Allow picking opponent's protect" is disabled in the round settings (next to # of protects setting)

Right-clicking a protected map removes its protected status the same way a right-click removes a pick or ban from a map. Right-clicking a protected map that has been picked first removes the pick, and a second right-click removes the protect.
