Migrate to SQLite for Internal Launcher Data

[Geometrically]

This PR migrates the launcher's internal data structure to be SQLite based. This allows for ease of updating, better performance, stability, and more.

This PR also changes the default launcher directory to fix issues with Minecraft NBT saving.

This should also fix several issues/bugs in the app, including:

• Profiles disappearing
• Freezing issues
• Infinite profile installs

This is still heavily WIP. TODO to merge:

• Re-add methods for managing a profile's projects (add, remove, list, disable/enable)
• Re-add profile groups
• Rewrite/reimpl FS watcher for crash reports and caching profile projects
• Reimplement updating and update-checking functionality for projects
• Re-add ability to change launcher directory
• Add migrators for existing launcher users to migrate to SQLite database
• Move Minecraft Auth Data to SQLite DB
• Move Modrinth Credentials to SQLite DB
• Move Process Manager to SQLite DB
• Fix/test profile importers (both external launchers and modrinth packs)
• Fix/test Modrinth pack exporting
• Update UI for compatibility with API changes
• Remove constant offline mode check
