Add AnyTagEqualTo and multi-clause support to VectorStoreTextSearch LINQ filtering

- Extend ConvertTextSearchFilterToLinq to handle AnyTagEqualToFilterClause
- Add CreateAnyTagEqualToExpression for collection.Contains() operations
- Add CreateMultipleClauseExpression for AND logic with Expression.AndAlso
- Add 4 comprehensive tests for new filtering capabilities
- Add RequiresDynamicCode attributes for AOT compatibility
- Maintain backward compatibility with graceful fallback

Fixes #10456
