Remove benchmarks for deprecated (or soon to be) features

[mtreinish]

Summary

This commit removes benchmarks for the deprecated assemble module and the soon to be (see #13063) deprecated pulse module. While these features are still supported it's not worth the spending the limited CPU time we hacve on the benchmarking system to track the performance of these components anymore.
