Revert "[nojit] Don't expose wasm in jitless mode"

This reverts commit c79a63e6.

Reason for revert: Needs addtl test skips: https://chromium-review.googlesource.com/c/1470124

Original change's description:
> [nojit] Don't expose wasm in jitless mode
> 
> Wasm currently still creates executable memory even in
> interpreter-only mode, and is thus unsupported in jitless mode. This
> hides wasm completely, which will help e.g. fuzzers that attempt to
> run wasm code (and currently crash on the CHECK in AddOwnedCode).
