[Backport] Security bug 366635354

Manual cherry-pick of patch originally reviewed on
https://chromium-review.googlesource.com/c/v8/v8/+/5872631:
Merged: [wasm] Do not inline wrappers with 'ref extern' parameter type

This was introduced in https://crrev.com/c/4212394.

The wrapper would need to test for null and throw a type error but
doesn't do that correctly.
(The test case added only tested that a null check happens either in
the wrapper or in the cast instruction because the test case was trying
to test both cases without duplicating too much which was a bad design
choice.)

For simplicity, just disallow inlining of wrappers with parameters
typed 'ref extern'. (Users should use `externref` aka 'ref null extern'
instead anyways as the non-nullability doesn't add any benefits.)

(cherry picked from commit 3eee872739ac3523af126d7f25a623c18f5bee39)
