Add AnalyzeSelectFilter Views plugin for dropdown filters

[jjroelofs]

Summary

Add a reusable Views filter plugin that provides select dropdown functionality for analyze submodules.

Supports three ways to populate options:

1. options_callback - Service method callback (e.g., analyze_ai_sentiments.storage:getSentimentOptions)
2. options_table - Database table with id/label columns
3. Fallback - Query distinct values from the filter's field

Also includes:

• Fix docblock parameter order in ContentInfo.php
• Standardize submit button to "Apply filters" in analyze_google_analytics view

Test plan

• Enable an analyze submodule that uses this filter (sentiments, security audit, or marketing audit)
• Verify the filter renders as a select dropdown instead of text input
• Run drush cr to rebuild caches after enabling
