Clarify MobileFormatter serialization limitations for collections

[rockfordlhotka]

Summary

Updated documentation across multiple versions to clarify that standard .NET collection types (List<T>, Dictionary<K,V>) are not directly serializable by MobileFormatter, and provide guidance on proper alternatives.

Key Changes

• Removed misleading references to List<T> as a supported primitive type in serialization documentation
• Added prominent warning notices in three documentation files explaining that standard .NET collections require either:
  • Use of CSLA-specific alternatives (MobileList<T>, MobileDictionary<K,V> from Csla.Core)
  • Custom serializer registration
• Reorganized the "Other" types section to clarify char[] is supported as a primitive type
• Applied consistent documentation updates across v9, v10, and main documentation branches

Notable Details

• The changes address a common source of confusion where developers might assume standard .NET collections work with MobileFormatter
• Warning notices use consistent formatting and messaging across all affected documentation files
• No functional code changes; documentation-only updates to improve clarity and prevent misuse
