port 2V2-c: chrmgr/chr modules + race registration chain

PythonCharacterManagerModule/PythonCharacterModule ported verbatim; the
2V0 chr/chrmgr stubs are gone and initchr/initchrmgr run in 40250 order.
The registration chain they need (RaceData/RaceDataFile/RaceManager/
RaceMotionData, GameType, AttributeData/AttributeInstance, TextFileLoader,
Util, Camera/CameraProcedure) is ported; CRaceManager is created in
PythonBoot. port.login_flow asserts race 0 has its wait motions and no
unhandled packet header; port.login_live 8/8 against 192.168.21.203.
