This prepares the `table_slice_builder` for the upcoming changes by doing some much-needed housecleaning.
Much like the `table_slice_builder`, some cruft accumulated on `msgpack_table_slice_builder` that needed to be removed.

The `table_slice::inspect` function must go through the constructor that handles the instance counting when loading table slices from a `caf::message`.
The offset being in the `table_slice` encoding-specific FlatBuffers tables was the only reason why we required support for mutable FlatBuffers. This commit changes `table_slice` to hold the offset in-memory. The offset is now assigned by the importer on import and by the segment on lookup.
The FlatBuffers API guarantees that the encoding pointers are not `nullptr`, so we might as well dereference them in the visitor function already.
