[leaysgur]

Prepare for next PR, which supports angular-(template|styles)

Pull request overview

This PR refactors the embedded code formatting interface to use language identifiers instead of tag names, improving separation of concerns between oxc_formatter and oxfmt. This prepares the codebase for future support of Angular templates and styles.

Changes:

• Renamed the format_embedded() parameter from tag_name to language to reflect the abstraction change
• Introduced language identifier mappings (e.g., css tag → "tagged-css" identifier, styled-jsx → "styled-jsx")
• Updated oxfmt to translate language identifiers to Prettier parser names, removing Prettier knowledge from oxc_formatter
