feat(es/minifier): Collapse let without init (#5909) 
**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.

**Description:**

We only unwrap parenthesis in precompress optimizer, so I refactored it. Also, as it's embarrassingly parallel, I parallelized it.
