[isoltest] Add bytecode builtin.

[aarlt]

Closes #10820.

[aarlt]

I think we need to support all possible kinds of bytecode's.

e.g. ir, irOptimized, legacy and legacyOptimized. Maybe also wast, ewasm and ewasm.wast?

@axic what do you think?

I guess that is true. I would ignore wasm for now. At the same time, cannot we say that bytecode remains as an option which must satisfy ir, irOptimized, legacy and legacyOptimized? If so, we can add the other kinds later when the need arises.

Still waiting for update I guess?

[leonardoalt]

Is this still wanted?

[leonardoalt]

This is marked as takeover but hasn't been active for a year, so I'm closing for now. Code is still available in the branch to whoever takes over.
