feat(Controller): environment map

[saitonakamura]

Allows to set env map and env map intensity on controller models via props.

Besised that, we found out a specific usecase when you want to update intensity without env map, so I split them into 2 methods. Perf should not suffer since most of this calls will be batched to a same frame
