Features: Team Game Spawn Color Tint (#2303)

## Description:

This PR addresses issue #2302: where there is no obvious information
about the self-player's team during the spawn phase of the game.

Currently, during TEAM games (where there is a set number of teams
defined), the self player's spawn highlight color is white, while all
other players are shown with a team-based spawn highlight color. This
makes it difficult to discern who is a teammate, especially since the
current live version (v0.26.7) uses green/yellow for other players to
depict teammate/other team, respectively.

Technically, the same is true for Duos, Trios, and Quads games, although
this has been addressed separately with PR #2298 by reverting to
green/yellow for teammate/other team players.

This PR changes the color of the self player's breathing spawn highlight
ring to match their assigned team color (with `alpha=0.5` for
transparency). The breathing ring is semi transparent on top of the
existing white static semi-transparent ring, giving the breathing ring a
**tint** of the team color instead of the exact team color.

This allows a player to immediately identify their assigned team and
maintains overall consistency with FFA, Duos, Trios, and Quads game
modes.

See below for example implementation. In this screenshot, the self
player is on the red team as shown by the red tint to the breathing
spawn highlight ring. The screenshot also shows some of the static white
semi-transparent ring around the spawn location. The self player's
teammate is to the top left of the image with a solid red spawn
highlight. The non-player (nation) opponent on the blue team is shown to
the bottom left. In online games, nations are not present in team games.
In single player or private lobby games they are shown as here, without
a spawn color highlight and only a territory color.
