Support spaceBeforeFunctionParens formatting rule

[galvez]

In StandardJS, there's always a space before a function's parenthesis:

- function foobar() {
+ function foobar () {

The main reasoning I think it's that it makes instantly easier to search for a function definition by just adopting the convention that no space means it's a call, space means it's a definition.

Overall, it would be nice to be able to fully replicate StandardJS with Biome.

My apologies, I see that this is a duplicate of #1193 — still I think this makes for a worthwhile addition, despite the acceptedly rational draconian approach of maintaining the rule set minimal.

Closing because of duplication.
