fix(napi): Read reference ownership before calling finalizer to avoid crash (#24203)
Fixes #23493.

What was happening here was that napi-rs was freeing the napi reference
([here](19e3488efc/crates/napi/src/bindgen_runtime/mod.rs (L62)))
during its finalize callback (which we call
[here](fb31eaa9ca/cli/napi/js_native_api.rs (L132))).
We then were [reading the `ownership`
field](fb31eaa9ca/cli/napi/js_native_api.rs (L136))
of that freed reference.

For some reason on arm macs the freed memory gets zeroed, so the value
of `ownership` was `0` when we read it (i.e. it was
`ReferenceOwnership::Runtime`). We then freed it again (since we thought
we owned it), causing the segfault.
