Request one separate compilation batch for each GPUPass so users can
get a better sense of the compilation progress, and to better distribute
texture loading over time.

With the new closure approach, the code can be simplified and cleaned up quite
a bit.
This also removes four parameters, which is helpful for future additions (!123616)
since the parameter limit appears to be reached.

The goal of this task is to remove noise in the most common material
layering configuration.
Subsequently, this also split the evaluation of different closure to
their own buffer to avoid discontinuity when denoising them.
This commit does a few things:
- [x] Removes use of global for closure random number.
- [x] Refactor the forward evaluation to be closure type agnostic.
- [x] Refactor the gbuffer lib to be closure type agnostic.
- [x] Reduces the number of picked closure to 3 maximum or less.
- [x] Use GPU_MATFLAG_COAT to tag the use of multiple usage of glossy BSDF.
- [x] Use two closure bin for Glossy when more than one.
- [x] Set closure bin per type for best noise level for most materials.
- [x] Change the gbuffer header to put the closure at their bin index.
- [x] Add a method to get a closure from the gbuffer from a specific bin.
- [x] Split lighting passes per Closure.

The benefits are removing unnecessary reallocations of the string data
and unnecessary recalculations of the size, better type safety, and more
automatic memory management.
