hablich 3b1b544c20 Revert of [wasm] Refactor import handling for 0xC. (patchset #10 id:180001 of https://codereview.chromium.org/2390113003/ )
Reason for revert:
Failes a few GC stress tests.https://chromegw.corp.google.com/i/client.v8/builders/V8%20Linux%20-%20gc%20stress/builds/6253

Original issue's description:
> [wasm] Refactor import handling for 0xC.
>
> Imports and exports in 0xC can be much more than functions, including
> tables, memories, and globals. This CL refactors the underlying
> organization of imports and exports to support these new import types.
