Z Nguyen-Huu 1f7861c8a9 Reland "[wasm] Tierdown wasm module upon "Debugger.enable"" 
This is a reland of 410ca4c50e

Skip new test for unsupported liftoff architecture.
Previously, if there is some unsupported liftoff functions, it fall
through Turbofan but recompilation didn't catch and count it. This CL
fixes it by using requested_tier on finished units.

Avoid to tier down asm.js.
Introduce reached recompilation tier to monitor recompilation progress.

Original change's description:
> [wasm] Tierdown wasm module upon "Debugger.enable"
>
> Put a logic in Wasm Engine to tier down all existing modules per isolate
> when debugger is enabled. This CL does not handle new module added after
> debugger is enabled yet.
