Revert of [wasm] Embedder can control what buffers wasm compilation works on. (patchset #3 id:60001 of https://codereview.chromium.org/2699843003/ )

Reason for revert:
Introduces a new test failure/flake: https://build.chromium.org/p/client.v8/builders/V8%20Linux/builds/16427

Original issue's description:
> [wasm] Embedder can control what buffers wasm compilation works on.
>
> Two controls, one for instantiation and one for compilation. They allow
> the embedder (e.g. Chrome) check properties of the parameters of those
> two operations, and decide if they are allowed to continue.
>
> For example, Chrome may now decline compilation of certain size buffers,
> in synchronous cases; same for instantiation (where the buffer size
> refers to the size of the buffer containing wasm wire bytes)
>
