Add emissive_exposure_weight to the StandardMaterial (#13350) 
# Objective

- The emissive color gets multiplied by the camera exposure value. But
this cancels out almost any emissive effect.
- Fixes #13133
- Closes PR #13337 

## Solution
- Add emissive_exposure_weight to the StandardMaterial
- In the shader this value is stored in the alpha channel of the
emissive color.
- This value defines how much the exposure influences the emissive
color.
- It's equal to Google's Filament:

## Testing

- The result of
[EmissiveStrengthTest](https://github.com/KhronosGroup/glTF-Sample-Models/tree/main/2.0/EmissiveStrengthTest)
with the default value of 0.0:
