…instance property initializer (#10492)

Move the `instance_inits_scope_id` and `instance_inits_constructor_scope_id` fields from the `ClassProperties` struct to local variables.

Using struct-level fields as temporary variables is unnecessary within three function depths, and you also need to consider when to reset the states, otherwise, you may cause a bug due to using previous temporary information. Moreover, I think it also improves a bit readability.

NOTE: This is not only a refactor, but also along with #10495 and #10493 to prepare #10491.

…rs scopes until all instance properties are transformed (#10495)

Re-parenting the initializers' scope after all instance properties are transformed, which is preparing for #10493. And rename `transform_instance_initializer` to `reparent_initializers_scope` because the previous name confused me; the implementation only affects scope data.

Moreover, there is a drawback to this change. The `reparent_initializers_scope` method now processes initializers that have been transformed, so that it will visit many unrelated AST nodes. See the transformer/pdf.js benchmark, it shows `0.1ms` slower than before. It may not matter; we will get it back in the follow-up changes.

… method only once (#10493)

Benefit from #10495, we can move getting `instance_inits_scope_id` and `instance_inits_constructor_scope_id` part to after all instance properties transformed. So that we can avoid to get `constructor` twice due to borrow checker.

Follow-on after #10493. We no longer locate the class constructor here.
