[core] Chocobo Racing packets and binding

[sruon]

I affirm:

• I understand that if I do not agree to the following points by completing the checkboxes my PR will be ignored.
• I understand I should leave resolving conversations to the LandSandBoat team so that reviewers won't miss what was said.
• I have read and understood the Contributing Guide and the Code of Conduct.
• I have tested my code and the things my code has changed since the last commit in the PR and will test after any later commits.

What does this pull request do?

• Introduces a single binding streaming the entire race to a player.
  • You build the whole race upfront and the client receives it before the event even starts.
• Adds proper definitions to each involved packet + constructors

local sendRaceData = function(player, race)
    player:sendChocoboRace({
        counter    = race.counter,
        weather    = race.weather,
        chocobos = race.chocobos,    -- The racing chocobos
        sections    = race.sections,      -- The actual race, in 32 sections
        places       = race.places,         -- Final results
    })
end

Holding back the lua changes for now since I still need to validate all event parameters and document the mechanics

Steps to test these changes

This is entirely generated with random chocobos, using actual race mechanics (items, stats, stamina etc)

Started documenting a little bit
