fix(es/utils): Fix wrong apis (#4604) 
# API Changes

## `swc_ecma_utils`

### Renames

 - `find_ids` => `find_pat_ids`
 - `prepend` => `prepend_stmt`
 - `as_bool` => `cast_to_bool`
 - `as_number` => `as_pure_number`
 - `as_string` => `cast_to_string`
 - (`as_pure_bool`, `cast_to_number` is not renamed)
 - `UsageFinder` => `IdentUsageFinder`.
 - `IdentFinder` => `IdentRefFinder`.

## Changes

 - Re-export of `HANDLER` from `swc_common::errors` is removed. Use `swc_common::error::HANDLER` instead.
 - Re-export of `Id` from `swc_ecma_ast` is removed. Use `swc_ecma_ast::Id` instead.
 - `ExprCtx` is used for apis related to `Expr`.
 - `preserve_effects` is now a method of `ExprCtx`. It was a top-level function.
 - `extract_side_effects_to` is now a method of `ExprCtx`. It was a top-level function.
 - `IdentUsageFinder` (previously `UsageFinder`) now takes `Id` instead of `Ident`.
 - `IdentRefFinder` (previously `IdentFinder`) now takes `Id` instead of `Ident`.
 - `ExprExt::is_ident_ref_to` is removed.
 - `Expr::is_global_ref_to` is added.
 - `:🆔:id` is removed. Use `Ident::to_id()` instead.

feat(es/resolver): Use different syntax context for unresolved refs (#4436) 
- We don't need a list of bindings to check if an identifier is unresolved.
 - Checking if an identifier is unresolved is now one CPU instruction.
   - Previously it was one hashmap operation.
 - This PR also improves performance, by removing the hashmaps mentioned above.
