Move mutation-related files to a new mutation/ directory. The names are kept in the global namespace to reduce churn; the names are unambiguous in any case. mutation_reader remains in the readers/ module. mutation_partition_v2.cc was missing from CMakeLists.txt; it's added in this patch. This is a step forward towards librarization or modularization of the source base. Closes #12788
