before this change, we rely on the default-generated fmt::formatter
created from operator<<, but fmt v10 dropped the default-generated
formatter.
in this change, we define formatters for canonical_mutation

the `utils::UUID` class is not used by the implementation of
`canonical_mutation`, so let's remove the include from this source file.
the `#include` was originally added in
5a353486c6, but that commit did
add any code using UUID to this file.

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
