Mesh.MeshData.SetVertexBufferParams function is not compatible with Burst
SetVertexBufferParams function of Mesh.MeshData uses params VertexAttributeDescriptor[] attributes that doesn't compile with Burst. There should probably exist an overload that takes NativeArray<VertexAttributeDescriptor>.

This just bit me. The worst part is it's a silent bug. I was using the version of SetVertexBufferParams
that uses VertexAttributeDescriptor[] and it worked in a job with [BurstCompile].
When I switched to the NativeArray version, the resulting Mesh was just empty.
As soon as I removed the [BurstCompile] attribute from the IJob the resulting Mesh worked as intended.
Thankfully, I at least got a nice performance boost from eliminating the managed array from the job. But only after figuring this out.
