[Wasm-GC] Implement initial minimal JS API for Wasm GC
https://bugs.webkit.org/show_bug.cgi?id=246769
Reviewed by Yusuke Suzuki.
Implements the Wasm GC draft JS API described in:
https://docs.google.com/document/d/17hCQXOyeSgogpJ0I0wir4LRmdvu4l7Oca6e1NkbVN8M/
https://github.com/WebAssembly/gc/pull/352
This specifies that GC structs and arrays are opaque objects with
internal methods (on WebAssemblyGCObjectBase) that either lead to
throwing exceptions or returning some kind of null result.
This patch doesn't yet implement the ToWebAssemblyValue changes needed
to roundtrip these values back to Wasm or to access globals and tables
with these values from JS.
The patch also eliminates some of the restrictions on passing GC values
that were added before the JS API was specified.

* JSTests/wasm/gc/js-api.js: Added.
