[Wasm GC] Stop printing deprecated cast etc. instructions (#5852)

Stop printing `ref.as_i31`, `br_on_func`, etc. because they have been removed
from the spec and are no longer supported by V8. #5614 already made this change
for the binary format. Like that PR, leave reading unmodified in case someone is
still using these instructions (even though they are useless). They will be
fully removed in a future PR as we finalize things ahead of standardizing
WasmGC.
