[llvm-exegesis][NFC] Disassociate snippet generators from benchmark runners The addition of `inverse_throughput` mode highlighted the disjointedness of snippet generators and benchmark runners because it used the `UopsSnippetGenerator` with the `LatencyBenchmarkRunner`. To keep the code consistent tie the snippet generators to parallelization/serialization rather than their benchmark runners. Renaming `LatencySnippetGenerator` -> `SerialSnippetGenerator`. Renaming `UopsSnippetGenerator` -> `ParallelSnippetGenerator`. Differential Revision: https://reviews.llvm.org/D72928
