converting_mutation_partition_applier is a heavyweight class that is not used in the hot path, so it can be safely out-of-lined. This moves some includes to boost/multiprecision out of header files, where they can infect a lot of code. mutation_partition_view.cc's includes were adjusted to recover missing dependencies.
