Add user season score calculation workflow

[venix12]

Part of #8736.

Serving as a base for implementation of seasonal rankings in nearing feature.

This mimics the Beatmap Spotlights seasonal rankings calculation process that used to be done via an external script.

Also adds an artisan command for score recalculating.

Tried to optimize the calculation process as much as possible, any further potential improvements on that matter would be vastly appreciated. 🤔

How does this work?

Rooms

1. The seasons are designed as a series of few (currently: three) playlists that are usually labeled by consecutive letters of alphabet (A, B, C).

2. Each of the playlists is ran twice over a course of the season. For the sake of this implementation, the rooms of the first run of the playlists are referred to as "parent rooms", while the rooms of the second run are called "children rooms".

This PR adds parent_id field to the multiplayer_rooms table, to be used on children rooms.

Score calculation

Total (user) season score is sum of best playlist total scores achieved throughout the season, with added factor-based weighting.

1. Total scores of a each playlist are compared between the parent and child rooms, with higher being taken for total season score calculation.

2. Said scores are sorted from highest to lowest, and season-specified factors are being applied in descending order to each of them (e.g. 1.0, 0.75, 0.5). This results in final total season score.

This PR adds the following:

• user_season_scores table, total_score of which is calculated using related model calculate() function, that is called whenever user places a score on related season's room.
• season_score_factors table, that stores factors, used for total season score calculation.

Example user total season score calculation

Let's say a user achieves following scores during the six playlists of the season:

playlist	score (parent)	score (child)
A	10	12
B	20	15
C	5	40

The season score factors are set to following: 1, 0.75, 0.5.

Playlist final scores are being sorted in descending order, resulting in following values: 40, 20, 12. The final season score calculation goes as below:

40 * 1 + 20 * 0.75 + 12 * 0.5 = 40 + 15 + 6 = 61

The total season score is 61. That value would be used for sake of placing user in seasonal leaderboard.
