[scheduling] Add optional schedule optimization for dynamic throughput

Adds a new codegen/scheduling flag `--dynamic_throughput_objective_weight`. This controls how strongly the SDC scheduler will attempt to optimize for dynamic throughput as opposed to area. If set to `K`, XLS will roughly consider decreasing the dynamic throughput of one state element by one cycle to be worth adding up to `K` flops, under the assumption that all data-dependent state-feedback paths are equally likely.

This was motivated by the discovery of a real-world case where it's possible to improve throughput substantially while sacrificing approximately one flop's worth of area.

Disable equivalence verification in tests when MSAN is enabled

Z3 is enough slower when MSAN is enabled that this substantially increases timeouts - and does not improve coverage, since we also run these tests with MSAN disabled, and Z3's proof's validity should not depend on whether the sanitizer is enabled.
