Fixes #87486
The Compatibility renderer currently assumes that all vertex colours are stored as sRGB and uses them as is. For files where the vertex colours are stored as linear (e.g. glTF) this means they appear much darker than intended. This PR adds a linear -> sRGB conversion when
vertex_color_is_srgbis false and Compatibility is being used.
