* Refactor instance_traits_util and add unit tests tests
* Address reviewer comments.
Just adds some TODOs to indicate deprecated layouts in our reflection. Our strategy is to leave the reflection code broad (covering deprecated features), but keep the builder concepts narrow. Once we've removed deprecated features from all instances, we can remove them from reflection.
Also add a comment to the cmake to explain the unit test target test_conv_builder.
* Addressed more reviewer comments.
* Remove duplicate PassThrough::name
Accidentally added this field to the end of the struct, too. The `name` field should be a the start of the struct for consistency.
