URenderPipeline: Use transformed attribute names in VertexFormat for RenderPipeline

Pretty much the same issue as d6937c4 but in the code for 1.21.5+ which
no longer supports MCShader uses the new vanilla RenderPipeline
mechanism instead.

This fixes draws with custom shader on graphics drivers which do not
order attributes by default by their order in the shader source code
(mainly MacOS).
