Remove externref (#4633)

Remove `Type::externref` and `HeapType::ext` and replace them with uses of
anyref and any, respectively, now that we have unified these types in the GC
proposal. For backwards compatibility, continue to parse `extern` and
`externref` and maintain their relevant C API functions.
