[Wasm] Unify IPInt's prepare_call and prepare_call_indirect paths
https://bugs.webkit.org/show_bug.cgi?id=312403
rdar://174857273
Reviewed by Yijia Huang and Yusuke Suzuki.
prepare_call_indirect and prepare_call_ref return the target instance
in r1 (via WASM_CALL_RETURN), but prepare_call always returned the
caller's instance, relying on import stubs to switch instances later.
For wasm-to-wasm imports, prepare_call now returns the target instance
and the real entrypoint, bypassing the wasm_to_wasm_ipint_wrapper_entry
stub. JS imports are unchanged, they still return the caller instance
and the import stub, which handles the transition. Although, I updated
comments to better reflect this happens.
This also removes stale commented out instance-swapping code from
mintAlign(_call) in the asm.
No new tests, covered by existing tests. No behavior change.
