@graphics/osl: import osl-1.15.7.0

Open Shading Language (OSL) is a small but rich language for
programmable shading in advanced renderers and other applications,
ideal for describing materials, lights, displacement, and pattern
generation.

OSL was originally developed by Sony Pictures Imageworks for use
in its in- house renderer used for feature film animation and visual
effects, released as open source so it could be used by other visual
effects and animation studios and rendering software vendors. Now
it's the de facto standard shading language for VFX and animated
features, used across the industry in many commercial and studio-
proprietary renderers. Because of this, the work on OSL received
an Academy Award for Technical Achievement in 2017.
