4b49cf8ce4 feat(transformer): always pass in symbols and scopes (#5087) 
We no longer need to build semantic data inside the transformer.

The caller should be responsible for handling semantic data and its
errors.

The best way to achieve this in via `CompilerInterface`.

feat(linter/no-unused-vars): delete non-root arrows, skip await (#5083) 
This PR updates no-unused-var's fixer for `VariableDeclarator`s in two
ways:
1. Unused function expressions and arrow functions not declared in the
top scope
   will now be removed.
   ```ts
   // not deleted, no change
   const x = function() {}
   const y = (a) => a
   function z() {}

   // new behavior
   function foo() {            // <- not deleted
       const x = () => {}      // <- deleted
       const y = function() {} // <- this too
   }
   ```
2. Variables initialized to an `await` expression will not be deleted.
   ```ts
// unused await-initialized variables are often API calls with side
effects
   // in the real world; we don't want to delete these.
   const res = await createUser(data)
   ```

3b353321ad fix(transformer/logical-assignment-operators): fix semantic errors (#5047) 
Fix semantic error caused by `clone_in` causing `reference_id` to not exist.

In this PR, I try to use `move_expression` as much as possible instead of `expr.clone_in`. But in some cases, we need to reuse the same expression in multiple places. I have added a `clone_expression` to workaround it

I felt a bit painful we missing a [clone_in_scope](https://github.com/oxc-project/oxc/issues/4804) API

ee7ac8b0b7 refactor(semantic): store all data in PostTransformChecker in transform checker (#5050) 
Pure refactor of transform checker. Store all scope data in `PostTransformChecker` so it doesn't need to be passed around. `SemanticData` contains a full set of all semantic data for semantic pass, so we have 2 instances of it for 1. after transform and 2. rebuilt semantic.
