fix(formatter,oxfmt): Remove redundant space after soft_line_break_or_space

[leaysgur]

Fixes #20548

Remove redundant Space elements that immediately followed soft_line_break_or_space() in three places:

• Arrow function chain signatures
• class ... extends with member expressions
• interface ... extends with member expressions

This, in turn, fixes the js-in-vue issue.

---

The root cause is that to_prettier_doc cannot fully replicate the oxc_formatter printer's runtime behavior (e.g. deduplication of spaces).

While this commit fixes the three identified IR-level issues, there are other known divergences between the printer and to_prettier_doc (e.g. Space → StartTag → Space patterns around comments) that will be addressed separately...

TL;DR, converting between Prettier Doc and oxc_formatter IR doesn't seem to be straightforward after all. 🥲
