Prewarms the shader variants for a given Shader that are in a given ShaderVariantCollection, using a given rendering configuration.
For information on shader loading and prewarming, including a list of different prewarming techniques, see Shader loading.
On modern graphics APIs, such as DX12, Metal, and Vulkan, the graphics driver uses the vertex data layout when it creates shader progams. This method allows you to specify the vertex data layout, and therefore correctly prewarm shader variants for these graphics APIs.
