Fixes #3197

[fschutt]

@syrusakbary wasmtime has a different architecture in this section, which is why they can just return self.vec.len() for the minimum, while we use a "descriptor", so we have to update it every time the table is grown or shrunk.

[syrusakbary]

We need to address this based on today's latest review (check the length, not just the descriptor minimum, on link time)

[syrusakbary]

It looks great, although we forgot to update the is_memory_compatible with the same fix as we did in the table

[fschutt]

@syrusakbary yeah I wasn't sure if I should do that

[syrusakbary]

As long as that's done we should be good to merge

LGTM 👍

I've got a couple queries, but they're more so I can understand the decision (e.g. u32 vs usize) or to make troubleshooting test_table_grow_3197() easier if it ever fails down the track.

@syrusakbary I have no idea why the Linux CI doesn't run, otherwise tests should pass now.
