feat: add taskbar lyrics real-time sync with adjustable delay slider

[Nynele]

Summary

This PR adds a real-time synchronized lyrics widget directly to the Windows taskbar using LRCLIB.

Motivation

Currently, there is no built-in widget to view real-time synced lyrics next to the taskbar widget. This addition enhances the music flyout experience by fetching and displaying lyrics dynamically as the song plays.

Type of Change

• Feature
• Bug fix
• Refactor (no functional changes)
• Style (formatting, naming)
• Other

What Changed

• Created TaskbarLyricsControl to handle LRCLIB lyrics queries, matching, real-time sync, and animation transitions.
• Implemented marquee scrolling behavior for long lyrics lines.
• Added user settings page (TaskbarLyricsPage) allowing users to enable/disable lyrics, change position relative to the taskbar widget, toggle click-to-open settings, and adjust a millisecond delay offset slider (from -2000ms to 2000ms).
• Integrated settings variables and localization strings (English/Spanish).

Additional Information

Note

The settings page currently uses the visualizer banner image (FluentFlyoutTaskbar-NoTitle-Zoomed.png). Please feel free to replace it with a lyrics-specific banner image when merging.

Checklist

• Code changes are manually tested and working.
