[Wasm-GC] Update element segments to account for typed funcrefs and GC types
https://bugs.webkit.org/show_bug.cgi?id=251874
Reviewed by Justin Michaud.
Fix element segment parsing to allow more kinds of ref types (this is actually
a requirement of the reference types proposal, predating both typed funcref and
GC).
Also add support for general const expr initialization for elements.
For now, initialization steps for element segments are done each time on table
init or array.new_elem. This could be done earlier in module init instead (to
avoid duplciated work for shared elements), but that requires a larger change
to create a runtime representation of elements that can strongly hold
references.
Add missing spec tests and re-enable tests that now succeed as well. A small
validation fix was needed for the br_table test.
