Historical character mappings

[CarbonY26]

For historical characters incoming from Vic3 where we have portraits for in HOI4, we could have something akin to the following:
link = { name = "___" last_name = "___" portrait = "/gfx/portraits/___/___" small_portrait = "/gfx/interface/ideas/___" }

A real example which we could map:
link = { name = "Henry" last_name = "Ford" portrait = "/gfx/portraits/BRA/portrait_BRA_henry_ford.dds small_portrait = "/gfx/interface/ideas/portrait_BRA_henry_ford_small.dds" }
