Add Strata wrap-sub-surface lighting support.
...
This is the initial version for supporting wrap lighting with Strata, allowing to convert legacy subsurface surface into Strata. This initial version is not fully correct (energy perservation is not correct due to non-normalized phase function, which needs to be revisited).

* Add SSS phase function support to Strata (only used for 'single scattering as transmission' on SSS material).
...
* Change SSS type to allows more enums. This will be used by SSS wrapping mode later on.
* Add bool for enabling/disable light diffusion on Strata material (on by default).
* Fix shader compilation issue on preview material due to decal code
