Fix a Parser Idempotency Issue (#3172)

* Fix a Parser Idempotency Issue

This PR fixes #3133 by correctly implementing `ToIndentedString`
for `with` statement.

It also replaces the existing `ToInternedString` implementation
because it is implemented for all types implementing
`ToIndentedString` in `boa_interner/src/lib.rs`.

* Add test for with statement formatting
