Revert "Change how vertex/instance attributes are handled in geometry processors."

This reverts commit 19c1233c447f625c2522e7ecd0a0adecc629bb2f.

Reason for revert: want to make sure Google3 can roll

Original change's description:
> Change how vertex/instance attributes are handled in geometry processors.
> 
> * No longer register vertex/instance attributes on base class, just counts
> 
> * Separate instance and vertex attributes and remove InputRate and offset
> 
> * Make attributes constexpr where possible
>
