Record human/nation/bot conquests (#2949)

## Description:

Conquests are currently mixing all player types.

This is not ideal as people wonders why a 50 player game can lead to
hundred of kills.
Having separate records can also help with achievements and better
balancing.

This PR splits the conquests record into 3 categories: human, nations
and bots.

It is linked to this infra PR:
https://github.com/openfrontio/infra/pull/246

While the recorded data make a distinction between bots/nations, it's
only displayed here as a single "bot" category.
