This changes the encoding of the {HandlerTable} from an array of Smi
values to a byte array. It allows embedding of said array into the
instruction stream of {Code} objects (similar to how safepoint tables
work). For interpreted bytecode the table is attached as a {ByteArray}
to the bytecode.
The advantage of this approach is a more compact encoding and also the
ability to move such tables easily off the GC'ed heap if needed (as is
done for WebAssembly code for example).
