[Wasm-GC] Add support for anyref
https://bugs.webkit.org/show_bug.cgi?id=247403
Reviewed by Justin Michaud.
Adds the anyref type that is the top type of the internal reference
hierarchy.
Also adds nullref, which is the bottom type of the reference hierarchy
and has no inhabitants except null. There is also a bottom type for
externrefs and funcrefs with different type codes, which should be added
in a separate patch.
Anyref becomes more useful once the `extern.internalize` and
`extern.externalize` instructions are added, which enable hostrefs that
inhabit anyref but are not eqref.
