fix(es/minifier): Don't replace parameters of IIFE if it's recursive (#5852)
**Description:**

While investigating, I found that problem is not the analysis of recursive functions. Instead, it was a problem with the IIFE evaluator, which replaces parameters even if it's recursive.

**Related issue:**

feat(es/minifier): Inline lazily initialized variables (#5737)
Safety:

For a function-local variable, an expression with side-effects would be a call, including an indirect one with a member expression.

 - If the call is function-local, it will be analyzed by the analyzer and inliner will not work.
 - If the call is not a function-local one, it cannot modify the local variable.

 - `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.

   - Previously it was one hashmap operation.
 - This PR also improves performance, by removing the hashmaps mentioned above.

- We now remap parameters using a new syntax context. This is required because we may copy functions, and it can result in duplicated variables with respect to the span hygiene.
 - We now visit the sequence expression generated by inlining. This is to improve performance in some cases.
 - We now remove variables from variable statements if it's identical to a parameter declared in the function.
 - IIFE evaluation is now aware of `this` being different for member expressions.
 - We now have more logic for detecting simple functions.
