joshua-spacetime 919908fb70 Trigger view refresh when a WASM procedure commits a transaction (#4301 )

# Description of Changes

This PR fixes the bug where WASM procedures could commit a transaction
without refreshing affected materialized views, which caused view-backed
subscriptions to miss updates from procedure writes.

The equivalent changes for V8 will be made in a separate patch.

# API and ABI breaking changes

None

# Expected complexity level and risk

This was not a simple translation of the reducer code path, because
reducers are run in a single transaction whereas procedures can have
multiple transactions via `with_tx` and views must be refreshed with
each transaction instead of once at the end of the procedure. This
required refresh to be inserted into the syscall itself which required
some extra plumbing. Mainly that we had to attach the validated
`ModuleDef` to the `WasmInstanceEnv`. This should not affect hotswapping
because we instantiate an entirely new `WasmInstanceEnv` in that case.

# Testing

- [x] Added a regression test in the form of a smoketest that subscribes
to a view and calls a procedure
