fix(rome_js_formatter): empty statements in if/else and do/while

[ematipico]

Summary

Closes #2448

I cherry-picked the implementation of the former PR, which aligns its behaviour to prettier.

The PR changes how if/else and do/while statements are formatted where the body is an empty statement, by matching Prettier's behaviour:

// before
if(a); else ;

// now
if (a);
else;

Test Plan

New tests to cover the case

It would help reviewers to add some more context to the PR summary. How does it format empty statements differently than before, in what cases. I otherwise have to open the issue, read through all the discussions or infer the logic from your changes which makes it hard to tell if the logic is working as intended.

I updated the description with a brief example of the changes.

Looks good. Would you mind generating the prettier report and posting how the metric changes with your PR?
