Kamil Braun b1d16c1601 types: move collection_type_impl::mutation(_view) out of collection_type_impl.
collection_type_impl::mutation became collection_mutation_description.
collection_type_impl::mutation_view became collection_mutation_view_description.
These classes now reside inside collection_mutation.hh.

Additional documentation has been written for these classes.

Related function implementations were moved to collection_mutation.cc.

This makes it easier to generalize these classes to non-frozen UDTs in future commits.
The new names (together with documentation) better describe their purpose.
