…P, and DEVRML Providers to accept non-const ReadStreamMap references

- Updated method signatures for Read and Write functions in DEIGES_Provider, DEOBJ_Provider, DEPLY_Provider, DESTL_Provider, DESTEP_Provider, and DEVRML_Provider to take ReadStreamMap by non-const reference.
- Changed usage of FindFromIndex to ChangeFromIndex for stream retrieval to allow modification of the stream map.
- Simplified error handling in DEOBJ_Provider and DEPLY_Provider by directly returning results from Read and Write calls.
- Enhanced error messages for empty stream maps and incorrect configuration nodes in DEVRML_Provider.
- Consolidated redundant code and improved readability across multiple provider implementations.

- Added validation functions for stream maps and configuration nodes to improve error handling and reduce code duplication.
- Introduced SetupApplication and ConfigureReaderFilter functions to streamline application setup and filter configuration.
- Refactored Read and Write methods to utilize the new validation and setup functions, enhancing readability and maintainability.
- Implemented ExtractShapeFromDocument to encapsulate shape extraction logic from documents.
- Improved error messaging for various failure scenarios during reading and writing processes.

…ion nodes, file paths, and streams

- Introduced DE_ValidationUtils for centralized validation functions across multiple providers.
- Replaced individual validation implementations for configuration nodes, documents, and stream maps with calls to DE_ValidationUtils.
- Improved error handling and warning messages for better clarity and consistency.
- Simplified the code structure by removing redundant validation functions and consolidating logic.
- Ensured that all providers now utilize the new validation utility functions for improved maintainability and readability.

- Removed multiple overloaded Read and Write methods in DEXCAF_Provider and DEBREP_Provider that handled streams, simplifying the interface.
- Updated the Read and Write methods to directly work with documents and shapes without the need for session parameters.
- Cleaned up the DEXCAF_ConfigurationNode by removing the IsStreamSupported method, as it was unnecessary.
- Enhanced error handling in the Read and Write methods to ensure proper validation and messaging.
- Consolidated application setup logic for better maintainability and clarity.

- Removed unnecessary blank lines and adjusted spacing in DEVRML_Provider.cxx and DEVRML_Provider.hxx for improved code clarity.
- Standardized parameter formatting in function declarations across DEVRML_Provider class.
- Enhanced readability in DEVRML_Provider_Test by aligning variable declarations and stream operations.
- Ensured consistent formatting in test cases, including spacing and line breaks, to adhere to coding standards.
