FrameCapture: Add ES 3.1 Vertex Attrib MEC support ES 3.1 adds new, more explicit ways to bind vertex buffers to different format combinations. This allows changing how data is interpreted without respecifying all the data as well. Apps using new ES 3.1 vertex attribute functions can be incompatible with our MEC setup that uses VertexAttribPointer. This was caught recently by Jamie's changes to enforce ES2 only conditions. Fortnite is the first app that uses ES3.1 semantics exclusively. To support this, add VertexAttribFormat and VertexAttribBinding to to our attribute setup loop. For binding indexes that *aren't* used with VertexAttibPointer, set them up with BindVertexBuffer.
