- Updated conditional compilation flags throughout the runtime codebase to transition from DART_DYNAMIC_MODULES to DART_BYTECODE_INTERPRETER. - Adjusted logic in various files including object_graph_copy.cc, object_reload.cc, profiler.cc, and others to ensure compatibility with the new interpreter model. - Ensured that all references to dynamic modules are replaced with bytecode interpreter checks, maintaining functionality for interpreted code execution. - Modified stack frame handling and service-related code to align with the new interpreter architecture. - Updated tests and service implementations to reflect the changes in the runtime environment.
