Add a property to control the bounce indirect energy in BakedLightmap

Browse Source 
Higher values will make indirect lighting brighter.
A value of 1.0 represents physically accurate behavior, but higher values
can be used to make indirect lighting propagate more visibly when using
a low number of bounces.

This can be used to speed up bake times by lowering the number of bounces
then increasing the bounce indirect energy. Unlike BakedLightmapData's
energy property, this property does not affect direct lighting
emitted by light nodes or emissive materials.

Global energy multiplier for baked and dynamic capture objects.
Global energy multiplier for baked and dynamic capture objects. This can be changed at run-time without having to bake lightmaps again.
To adjust only the energy of indirect lighting (without affecting direct lighting or emissive materials), adjust [member BakedLightmap.bounce_indirect_energy] and bake lightmaps again.
