[wasm-gc] Merge anyref and externref

Browse Source 
According to the latest changes in wasm-gc, externref will be renamed
to anyref, and will be assigned as the top of the reference type
hierarchy. Since in the current wasm type system funcref is not a
subtype of anyref, subtyping is now dependent on whether wasm-gc is
enabled.
