Revert "[wasm] Ensure that only TurboFan code is serialized"

This reverts commit 60ee70bb40efea6f05476dc19f7a5b490193a107.

Reason for revert: wasm-api-tests/WasmCapiTest.Serialize starts flaking: https://crbug.com/v8/10784

Original change's description:
> [wasm] Ensure that only TurboFan code is serialized
> 
> We have the implicit assumption that Liftoff code will never be
> serialized, and we start relying on that when implementing new features
> (debugging, dynamic tiering).
> 
> This CL makes the serializer fail if the module contains any Liftoff
> code. Existing tests are changed to ensure that we fully tiered up
> before serializing a module (similar to the logic in Chromium).
> The "wasm-clone-module" test needs to serialize the module before
> enabling the debugger.
> 
> Note that chrome currently only serializes a module after it fully
> tiered up, so that should be fine. If other embedders need the ability
> to serialize a module in an arbitrary state, we will have to fix this
> later. With this CL we will be on the safe side though and (gracefully)
> fail serialization instead of accidentally serializing Liftoff code.
