Metal: Convert index & vertex format on GPU when possible. - When converting vertex buffer: - if there is no render pass active, use compute shader to convert. - if there is a render pass active and device supports explicit memory barrier then convert the buffer in vertex shader with direct buffer write and insert a memory barrier. - if there is a render pass active and device doesn't support explicit memory barrier then convert the buffer on CPU.
