Guy Bedford ec7a28f2e0 module: cache compiled WebAssembly modules in the compile cache ...

Extends the module compile cache to WebAssembly modules loaded through
the ES module integration. A new kWasm entry type is keyed on the module
URL with the wire bytes as the hashed source, and stores the serialized
CompiledWasmModule. On load, cached code is deserialized through
v8::WasmModuleCompilation with the same compile options the translator
uses (js-string builtins and imported string constants), falling back
to compilation when V8 rejects it.

As for JavaScript, the cache entry is generated right after compilation.
V8 only serializes optimized tier code, so with the default lazy
baseline compilation there is nothing to cache and no entry is written;
a complete cache requires --no-liftoff --no-wasm-lazy-compilation, which
is documented as the way to use the compile cache for WebAssembly.
