fix(es/minifier): Fix analysis of parameters ( #5954 )
...
**Description:**
Although the author of the issue talked about `@react-pdf/renderer`, it's a bug related to `brotli`, not react pdf renderer.
After investigation, I found that the bug is caused by not marking parameters as initialized. So I fixed the analyzer.

**Description:**
This patch applies the variable collapsing logic for the variables declared with `var` to the variables declared with `let`. This requires some patch about the behavior of visitors about `BlockStmt`, so this patch includes relevant changes.

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.

# 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.
