Improve GameScriptLevel.

Rename LARA_DRAW_TYPE to LARA_TYPE as it's used in more than just drawing code. Make WEATHER_TYPE a scoped enum (would have done this for LARA_TYPE too but didn't want to pepper casts in other parts of the codebase). Relabel constants in both enums.

Add kLaraTypes and kWeatherTypes and add them as tables in GameFlow.

Remove Background member - it's not level-specific so GameFlow is a better home for it.

Add (incomplete for now) documentation for some GameScriptLevel members - those I tested, at any rate.
