refactor(formatter_test): refactor TestFormatLanguage trait

[ah-yu]

Summary

Part of #3334

The current TestFormatLanguage trait does not adapt to the new js formatter api, because we need to pass in other language formatters, and we also need to read other language settings. We can use the abstraction provided by the biome_formatter::format_node function to simplify the TestFormatLanguage trait to meet our needs.

pub trait TestFormatLanguage {
    type ServiceLanguage: ServiceLanguage + 'static;
    type Context: CstFormatContext<
        Options = <Self::ServiceLanguage as ServiceLanguage>::FormatOptions,
    >;
    type FormatLanguage: FormatLanguage<Context = Self::Context, SyntaxLanguage = Self::ServiceLanguage>
        + 'static
        + Clone;

    fn parse(&self, text: &str) -> AnyParse;

    fn format_node(
        &self,
        language: Self::FormatLanguage,
        node: &SyntaxNode<Self::ServiceLanguage>,
    ) -> FormatResult<Formatted<Self::Context>> {
        biome_formatter::format_node(node, language)
    }

    fn format_range(
        &self,
        language: Self::FormatLanguage,
        node: &SyntaxNode<Self::ServiceLanguage>,
        range: TextRange,
    ) -> FormatResult<Printed> {
        biome_formatter::format_range(node, range, language)
    }

    fn to_format_language(
        &self,
        settings: &Settings,
        file_source: &DocumentFileSource,
    ) -> Self::FormatLanguage;
}

Test Plan

CI should pass
