[Rust] Primary keys for query builder views (#4572 )

# Description of Changes

Query builder views return a subset of rows from a physical table. If
that table has a primary key, then so should the view. What this means
concretely is that the view should expose the same api as the table,
specifically as it relates to the primary key column.

With that in mind, this patch commits the following changes:
1. Annotates `ViewDef` with a `primary_key`
2. Updates the return type of query builder views in the raw module def
to a special product type
3. Adds an index for the primary key on the view's backing table
4. Updates the query planner to use this index
5. Updates rust client codegen to generate `on_update` for such views

# API and ABI breaking changes

None

Old `impl Query` views compiled with an older version of SpacetimeDB
will continue to work as they did before - without a primary key.

# Expected complexity level and risk

3

# Testing

- [x] New rust sdk integration suite exercising `on_update` for PK views
and semijoin scenarios
- [x] Smoketests for PK views and semijoin scenarios
